   OPINION AND ORDER

SHIRA A. SCHEINDLIN, UNITED STATES DISTRICT JUDGE

I. INTRODUCTION

This suit — against the New York City Department of Education (“DOE”) and its Chancellor, Carmen Fariña (collectively, the “City Defendants”) and the New York State Education Department (“NYSED”) and its Commissioner, MaryEllen Elia (collectively, the “State Defendants”) (together with the City Defendants, “defendants”) — is brought by the parents of eight New York City students who are classified as autistic under the Individuals with Disabilities Education Act (“IDEA”) and have individualized education programs (“IEPs”) pursuant to the IDEA. Plaintiffs allege that the City and State defendants have adopted certain systemic policies which impede the provision of adequate special education services to New York City students, in violation of federal and state law. Plaintiffs assert violations of the IDEA, Section 504 of the Rehabilitation Act of 1973 (“Section 504”), Section 1983 of Title 42 of the United States Code (“Section 1983”), the Due Process Clause of the Fourteenth Amendment, the New York State Constitution, and sections of the New York State Education Law.

In the instant motion, plaintiffs seek class certification of two classes and three subclasses under Rules 23(a) and 23(b)(2) of the Federal Rules of Civil Procedure. First, plaintiffs seek to certify an “NPS Class,” comprised of students who have been recommended for placement in a State-approved non-public school (“NPS” or “NPS Program”) and are subject to an alleged State-issued directive (the “NPS Directive”) that these schools provide all services set forth on a student’s IEP within the instructional day. Within the NPS Class, plaintiffs seek certification of two subclasses: the “Due Process NPS Subclass” and the “Lost Services NPS Subclass.” Second, plaintiffs seek to certify an “Autism Services Class,” comprised of autistic students who are allegedly subject to a City policy of refusing to recommend certain educational services to which plaintiffs are entitled (the “Autism Services Policies and Practices”). Within the Autism Services Class, plaintiffs also seek to certify the “Due Process Autism Subclass.” Additionally, plaintiffs seek appointment as class representatives and approval of their attorneys as class counsel.

For the following reasons, plaintiffs’ motion is GRANTED in part and DENIED in part. Class certification is (1) granted in full for the NPS Class and Due Process NPS Subclass; (2) denied for the Lost Services NPS Subclass; (3) and granted, as modified herein, for the Autism Services Class and Due Process Autism Subclass. For the surviving classes and subclasses, plaintiffs’ request for appointment as class representatives and approval of class counsel is granted.

II. BACKGROUND

A. Procedural History

In July 2013, student Y.G. and his parents, M.G. and Y.M., initiated this suit against the City Defendants only. Subsequently, seven additional students and their parents joined as plaintiffs and claims against the State Defendants were added. Class allegations were first asserted in the Third Amended Complaint, which was filed in May 2014. On August 28, 2015, plaintiffs moved for certification of two classes and three subclasses, appointment as class representatives, and approval of class counsel. The proposed classes and subclasses are defined as follows:

1. Proposed NPS Class and Subclasses

Plaintiffs D.D., K.S., Y.A., and E.H. seek to certify and represent the “NPS Class” of all

(i) children with disabilities under the meaning of the IDEA who (a) reside in New York City; (b) have IEPs; (c) were recommended for or attended an “NPS Program” and (d) have been subject to the NPS Directive and (ii) those who will, in the future, meet the criteria of (i).

Additionally, plaintiffs seek to certify two subclasses of the NPS Class. First, all proposed NPS Class representatives seek to certify the “Due Process NPS Subclass,” consisting of: “(i) members of the NPS Class who are, or were, receiving and will receive [Related] NPS Services; and (ii) who invoked or will invoke their due process [rights] and obtained stay-put rights under 20 U.S.C. § 1415(j).” Second, plaintiffs D.D., K.S., and Y.A. seek to certify and represent the “Lost Services NPS Subclass,” consisting of individuals who “(i) are members of the NPS Class whose [Related] NPS Services were removed from their IEPs; and (ii) all those who will, in the future, meet the criteria of (i).”

2. Proposed Autism Services Class and Subclass

All eight students bringing this action also seek to certify and represent the “Autism Services Class” and “Due Process Autism Subclass.” The Autism Services Class consists of all

(i) children diagnosed with Autism Spectrum Disorder ... under the [Diagnostic and Statistical Manual of Mental Disorders], or classified as autistic by the City Defendants under the IDEA, who (a) reside in New York City; (b) have IEPs; (c) have been subject to the Defendants’ Autism Services Policies and Practices; and (ii) those who will, in the future, meet the criteria of (i).

The Due Process Autism Subclass consists of “members of the Autism Services Class who have won or will win [Impartial Hearing Officer (“IHO”) ] or [State Review Officer (“SRO”) ] decisions, court orders, or entered into resolution agreements for Autism Services and who have been or will be subject to the Autism Services Policies and Practices.”

B. The IDEA

The IDEA is a federal statute regulating the education of children with disabilities. In exchange for federal funding, the IDEA requires participating states to provide disabled children with a free and appropriate public education (“FAPE”) and offer them and their parents certain procedural protections.

State and local educational agencies share the responsibility of complying with the IDEA. State Defendants are responsible for the “general supervision” of special education, including the development of IDEA-compliant policies and procedures. In carrying out these obligations, the State cannot “use a funding mechanism by which the State distributes funds on the basis of the type of setting in which a child is served that will result in the failure to provide a child with a disability FAPE according to the needs of the child.” Further, City Defendants are responsible for implementing “policies, procedures, and programs that are consistent with the State policies and procedures.”

1. FAPE and Related Services

A FAPE requires satisfying each student’s “unique needs and prepar[ing] them for further education, employment, and independent living.” To achieve this, the IDEA requires that each disabled student have a written IEP in place — developed with input from parents, evaluators, and teachers — and that this IEP is revised at least annually. The IEP must contain', inter alia, “a statement of the special education and related services and supplementary aids and services ... to be provided to the child, ... and a statement of the program modifications or supports for school personnel that will be provided for the child.”

“Related [SJervices ... are such developmental, corrective, and other supported services ... as may be required to assist a child with disability to benefit from special education.” Depending on a child’s needs, his or her “Related Services” may include “speech-language pathology, audiology services, interpreting services, psy-chologicál services, physical therapy, occupational therapy, rehabilitation counseling services, parent counseling and training, and assistive technology services.” If a local school district is unable to provide the Related Services required by a child’s IEP, parents can apply for a Related Services Authorization (“RSA”), which is “essentially a voucher for ... parents to find an appropriately licensed credentialed provider to provide the [R]elated [Services.”

2. NPS

The IDEA also permits school districts to place disabled children in NPS Programs instead of public schools. New York law offers four types of NPS for school-age children: (1) “private 853 schools” run by private agencies; (2) “Special Act School Districts” for “students who reside in child care institutions”; (3) privately-operated “State-supported schools”; and (4) “State-operated schools” for visually-and hearing-impaired students. Children attending NPS are nonetheless entitled to “all the rights [they] would have if’ attending a public school, and defendants remain responsible for providing a FAPE to NPS students in their jurisdiction.

3. Procedural Rights Under the IDEA

The procedural rights guaranteed by the IDEA include the right of parents to an impartial due process hearing regarding their child’s placement and services. In general, children are entitled to remain in their “then-current educational placement” during the pendency of these proceedings.

In New York state, the initial due process hearing is conducted before an IHO from the local educational agency. The IHO’s written decision is appealable to the New York State Education Department’s Office of State Review, where an SRO will examine the record and issue an “independent decision.” After exhausting this two-tiered administrative review process, an aggrieved party is entitled to seek judicial review in federal or state court.

C. The Alleged NPS Directive

Plaintiffs allege that on July 2, 2012, the State Defendants issued a' directive, by letter, stating that NPS students “would no longer be able to receive special education and related services unless those services were offered by or available directly through the particular NPS Program the child was or would be attending” (the “NPS Directive”). Defendants contend that the reason for this policy change was “that many ,[NPS] serving disabled children in New York City were relying on RSAs to provide [Rjelated [SJervices to students enrolled in their programs, in tension with the state education regulations.” Defendants also maintain that the shift toward requiring in-school Related Services was intended to benefit students and reduce out-of-sehool burdens on parents. In contrast, plaintiffs allege that the impetus for this directive was that City Defendants “were funding Additional [Related] Services ... deemed [by State Defendants] to be in excess of the pre-ap-proved funding ... allocated to each NPS Program.”

On July 27, 2012, the State Defendants issued another letter “clarifyfing]” that NPS “should accept only those students for whom the school could provide all the special education and [R]elated [S]ervices set forth on the student’s IEP, during the course of a school day, and without the need for the issuance of RSAs.” The July 27, 2012 letter also stated that “students currently receiving [R]elated [SJervices through an RSA need to continue to have the services provided until school-based services are available or an alternative school program has been identified.” A State employee later testified that “the direetive[] is related to [Rjelated [Services.”

Plaintiffs allege that in promulgating and carrying out the NPS Directive,

State Defendants ... (i) are foreclosing the possibility that severely disabled children can receive individualized special education; (ii) caused a large number of children with varying disabilities to lose a variety of services; (iii) are preventing [Related] Services without litigation; and (iv) have usurped the authority of the IEP teams in New York City.

As a result, plaintiffs contend, parents of disabled children attending NPS and requiring Related Services have been forced to choose between foregoing necessary services that cannot be provided by their NPS, forfeiting their child’s NPS placement, or initiating a due process hearing in hopes of being awarded the Related Services that they otherwise would lose.

State Defendants explain, however, that where circumstances prevent NPS from providing certain Related Services, the State can issue student-specific RSA exceptions. State Defendants assert that' “every such request that has been made has been approved” but note that “[t]hese circumstances usually involve very specialized needs for [R]elated [S]ervices.” Accordingly, “with very few exceptions, ... [R]elated [Services are no [longer] being provided through RSAs for [NPS] students.” During the 2013-2014 school year, NYSED received “approximately six” petitions for an RSA exception.

E. The Alleged Autism Services Policies and Practices

Separately, plaintiffs allege that the City Defendants have implemented certain Autism Services Policies and Practices that impermissibly impede consideration of “the full range of education services, supports, and accommodations ... contemplated by IDEA.” Plaintiffs define the Autism Services Policies and Practices as, “[i]n essence, Defendants^] restrictions on the ability of IEP Teams to recommend Autism Services (defined below) on an autistic child’s IEP.” Plaintiffs allege that because of these Autism Services Policies and Practices, the IEP process is “improperly influenced by blanket policies, as well as limitations on services,” subjecting autistic students to “non-individualized and de-facto restricted IEP meetings” and forcing them to file for due process hearings to secure certain accommodations that they require (the “Autism Services”). These Autism Services are defined in the Fourth Amended Complaint as:

(a) 1:1 instruction with a teacher for all or part of the day; (b) research-based instructional strategies, including, but not limited to, Applied Behavioral Analysis (“ABA”); (c) extended school day, after school or home-based services (for students attending a school-day program); (d) parent training at home; (e) services to promote inclusion; (f) training for staff; (g) rehabilitation training; (h) leisure training; or (i) instruction in a ratio smaller than 6:1:1 for students in a public school.

Plaintiffs further allege that even when Autism Services are awarded through due process hearings, defendants have a policy of terminating such services at the end of each school year — requiring parents to continually re-litigate their child’s entitlement to these services.

During depositions, a State employee confirmed that children should receive all special education services within the school day and stated that one-to-one instruction cannot be designated on IEPs. Additionally, State and City employees testified that IEP teams cannot include ABA services on an IEP. Plaintiffs allege that defendants made similar representations regarding ABA to parents during IEP meetings and due process hearings.

All plaintiffs filed due process challenges with respect to their IEP services, and all have been awarded ABA and other requested services through these proceedings. At least some plaintiffs have repeatedly filed such challenges over successive school years.

III. LEGAL STANDARD

A. Federal Rule of Civil Procedure 23(a)

Rule 23(a) permits individuals to sue as representatives of an aggrieved class. To be certified, a putative class must first meet all four prerequisites set forth in Rule 23(a), generally referred to as numer-osity, commonality, typicality, and adequacy. District courts have broad discretion in deciding whether to certify a proposed class under Rule 23.

“Rule 23 does not set forth a mere pleading standard. A party seeking class certification must affirmatively demonstrate [its] compliance with the Rule— that is, [it] must be prepared to prove that there are in fact sufficiently numerous parties, common questions of law or fact, etc.” Plaintiffs seeking class certification bear the burden of demonstrating by a preponderance of the evidence that the proposed class meets each of the requirements set forth in Rule 23(a). When assessing whether plaintiffs have met this burden, courts must take into account “all of the relevant evidence admitted at the class certification stage.” A court may certify a class only after determining that “whatever underlying facts are relevant to a particular Rule 23 requirement have been established.” This rigorous analysis requires examining the facts of the dispute, not merely the pleadings, and it will frequently “entail some overlap with the merits of the plaintiffs underlying claim.”

However, “[a] motion for class certification should not ... become a mini-trial on the merits.”’ At the class certification stage, “a district judge should not assess any aspect of the merits unrelated to a Rule 23 requirement.” Further, the court’s “determination as to a Rule 23 requirement is made only for purposes of class certification and is not binding on the trier of facts, even if that trier is the class certification judge.”

Additionally, “‘[e]ven after a certification order is entered, the judge remains free to modify it in light of subsequent developments in the litigation.’” “In fact, the court has a duty to ensure that the class is properly constituted and has broad discretion to modify the class definition as appropriate to provide the necessary precision.”

1.Numerosity

Rule 23(a)(1) requires that a class be “so numerous that joinder of all members is impracticable.” In the Second Circuit, sufficient numerosity can be presumed at a level of forty members or more. “The numerosity requirement in Rule 28(a)(1) does not mandate that join-der of all parties be impossible — only that the difficulty or inconvenience of joining all members of the class make use of the class action appropriate.” Courts do not require evidence of exact class size to satisfy the numerosity requirement.

2.Commonality

Rule 23(a)(2) requires that there be “questions of law or fact common to the class.” Commonality thus requires plaintiffs “to demonstrate that the class members ’have suffered the same injury.’” Commonality further requires that the claims asserted “must depend upon a common contention ... of such a nature that it is capable of classwide resolution — which means that determination of its truth or falsity will resolve an issue that is central to the validity of each one of the claims in one stroke.”

3.Typicality

Under Rule 23(a)(3), “[typicality ‘requires that the claims of the class representatives be typical of those of the class, and is satisfied when each class member’s claim arises from the same-course of events[ ] and each class member makes similar legal arguments to prove the defendant’s liability.’” The typicality requirement may be satisfied where “’injuries derive from a unitary course of conduct by a single system.’” Accordingly, “[t]he commonality and typicality requirements tend to merge into one another, so that similar considerations animate analysis of Rule 23(a)(2) and (3).”

The purpose of typicality is to ensure that class representatives “have the incentive to prove all the elements of the cause of action which would be presented by the individual members of the class were they initiating individualized actions.” A lack of typicality may be found in cases where the named plaintiff “was not harmed by the [conduct] he alleges to have injured the class” or the named plaintiffs claim is subject to “specific factual defenses” atypical of the class.

4. Adequacy

Adequacy under Rule 23(a)(4) “is twofold: the proposed class representative must have an interest in vigorously pursuing the claims of the class, and must have no interests antagonistic to the interests of other class members.” Thus, the question of adequacy “entails inquiry as to whether: 1) plaintiffs’ interests are antagonistic to the interest of other members of the class and 2) plaintiffs’ attorneys are qualified, experienced and able to conduct the litigation.” In order to defeat a motion for certification, any conflicts between the class representative and members of the putative class must be “fundamental.”

5. Implied Requirement of Ascertainability

Finally, in addition to the express requirements of Rule 23(a), the Second Circuit recognizes an “implied requirement of ascertainability.” “[T]he touchstone of ascertainability is whether the class is ‘sufficiently definite so that it is administratively feasible for the court to determine whether a particular individual is a member.’” Accordingly, “[a] class is ascertainable when defined by objective criteria that are administratively feasible and when identifying its members would, not require a mini-hearing on the merits of each case.” “The Second Circuit has cautioned against certifying overbroad classes, even under Rule 23(b)(2), which requires a less precise definition than Rule 23(b)(3).”

B. Federal Rule of Civil Procedure 23(b)(2)

If the requirements of Rule 23(a) are met, the court “must next determine whether the class can be maintained under any one of the three subdivisions of Rule 23(b).” Rule 23(b)(2) provides that an action may be maintained as a class action when “the party opposing the class has acted or refused to act on grounds that apply generally to the class, so that final injunctive relief or corresponding declaratory relief is appropriate respecting the class as a whole.” The Supreme Court “has clarified that certification of a class for injunctive relief is only appropriate where ‘a single injunction ... would provide relief to each member of the class.’” Additionally, “[i]t is appropriate for the court to consider the ‘inability of the poor or uninformed to enforce their rights and the improbability that large numbers of class members would possess the initiative to litigate individually.’”

C. Federal Rule of Civil Procedure 23(c)(5)

Rule 23(c)(5) authorizes the creation of subclasses “that are each treated as a class.” When “exercising its discretion to certify subclasses,” however, “a court must assure itself that each subclass independently meets the requirements of Rule 23.”

IV. DISCUSSION

A. Rule 23(a)

1. Proposed NPS Class and Subclasses

As discussed below, the proposed NPS Class and Due Process NPS Subclass fulfill Rule 23(a)’s requirements, but the proposed Lost Services NPS Subclass fails for lack of ascertainability.

a. Numerosity

Rule 23(a)(1) requires that the “class [be] so numerous that joinder of all members is impracticable.” Here, numer-osity is not disputed and is satisfied for the NPS Class and subclasses given that each would consist of far more than forty members. With respect to the NPS Class, defendants have represented that, as of July 2014, there were 8,227 children with IEPs attending NPS Programs in New York City (most of whom were placed through the City Defendants’ placement team). Additionally, with respect to the Due Process NPS Subclass, plaintiffs’ counsel represents that they have been contacted by parents of at least forty children who fit within this subclass’ definition. Lastly, with respect to the Lost Services Subclass, the State Defendants have provided information indicating that over one-thousand children have had their Related Services discontinued after the issuance of the alleged NPS Directive.

b. Commonality

Rule 23(a)(2) also requires that there be “questions of law or fact common to the class.” The NPS Class and subclasses satisfy the commonality requirement given that “the class members ‘have suffered the same injury’” and that their injuries are capable of class-wide resolution. All class members are alleged to have suffered a common injury due to the existence of a single, overarching policy: the NPS Directive. And as will be discussed, the record contains sufficient evidence establishing the existence of this policy. Further, any injury sustained by class members as a result of the NPS Directive is capable of, and likely best addressed by, class-wide resolution. Here, plaintiffs’ request for relief is limited to a single injunction that would address any illegalities that are identified in the NPS Directive. Issuing such an injunction would not require any individualized inquiry — including no inquiry into an individual IEP or entitlement to money damages.

Defendants offer two main arguments against commonality, neither of which is persuasive. First, relying primarily on the Supreme Court’s decision in Wal-Mart v. Dukes, defendants argue that plaintiffs have failed to establish the existence of the NPS Directive and thus, that there can be no commonality without this common source of injury. The NPS Directive does not, however, present the commonality problem identified in Wal-Mart. In WaV-Mart, plaintiffs sought to certify a nationwide class to challenge gender discrimination across the Wal-Mart chain. The Supreme Court held that the proposed nationwide class lacked commonality because there was insufficient evidence of a company-wide policy of discrimination. Instead, the Court found, Wal-Mart had a system of allowing local supervisors to make employment decisions on a discretionary basis — “just the opposite of a uniform employment practice that would provide the commonality needed for a class action.” Thus, the Court observed, “[wjithout some glue holding together the reasons for [the local supervisors’] decisions, it will be impossible to say that examination of all the class members’ claims will produce a common answer.”

In contrast to Wal-Mart, the record in this case offers substantial evidence of an overarching NPS Directive regarding the provision of Related Services. Specifically, it is undisputed that on July 2, 2012, State Defendants sent letters informing NPS, inter alia, that “all [Rjelated [SJervices for students enrolled in such schools are to be provided within the school’s education program” and that they “should not be offering admission to any student for whom it cannot provide the ... services recommended on the student’s IEP, including [R]elated [S]ervices[,] during the school day.” Further, the record indicates that defendants have acted in accordance with this directive, including sending followup letters, reviewing applications for RSA exceptions, and determining that “with very few exceptions, ... [RJelated [Sjervices are no [longer] being provided through RSAs for [NPS] students.” Even the City Defendants’ opposition brief concedes that “[p]laintiffs can credibly argue that members of [the proposed NPS Class] are all subject to the State directive.”

Despite this, defendants offer several inconsistent arguments challenging the existence of the NPS Directive. In some places, defendants maintain that they have “no such policy and ha[ve] issued no such directive.” As explained, the record contains substantial evidence that the NPS Directive was issued and implemented. Defendants argue elsewhere that plaintiffs have mischaracterized the NPS Directive because the policy was enacted to benefit students and parents, allows for RSA exemptions, and has not prohibited NPS students from receiving Related Services when their NPS cannot provide them. These arguments not only contradict defendants’ position that no such policy exists, but address the question of whether defendants violated the law (and if so, to what extent) — a merits question that is irrelevant to the commonality inquiry.

Second, defendants argue that the class members’ injuries are too individualized for class-wide resolution. This argument fails because it is based on a mis-charac-terization of plaintiffs’ claims and request for relief. Although the IEP process is necessarily individualized to each student’s needs, plaintiffs do not seek to vindicate individual students’ rights to the particular Related Service(s) they require. Rather, plaintiffs seek injunctive relief from limitations that the NPS Directive places on students’ access to Related Services overall — a matter that can and should be resolved on a class-wide basis.

c. Typicality

Further, the NPS Class and subclasses satisfy Rule 23(a)(3)’s typicality requirement because “[e]ach class member’s claim arises from the same course of events” — i.e., the NPS Directive and its effect on access to Related Services — and “each class member makes similar legal arguments to prove the' defendant’s liability” regarding these alleged restrictions. Defendants’ main arguments against typicality — that plaintiffs have failed to establish the existence of the NPS Directive and that class members require case-by-case (rather than class-wide) relief — overlap with their arguments regarding commonality. These arguments fail for the reasons explained above.

As an additional argument against typicality, defendants cite the conclusion of one class representative’s IHO that “any denial of FAPE to [the child] ... has in fact been remedied.” However, one IHO decision — issued within a student’s specific due process hearing — does not disprove the typicality of plaintiffs’ claims regarding the NPS Directive as it affects all class members. In fact, it is precisely this burden on families to file for due process hearings that plaintiffs seek to alleviate through a class-wide, systemic remedy,

d. Adequacy

Further, the proposed class representatives and counsel for the NPS Class and subclasses meet Rule 23(a)(4)’s requirement that they “will fairly and adequately protect the interests of the class.” The proposed class representative are children with IEPs who, as a result of the NPS Directive, have suffered the same harm alleged on behalf of each class member—namely, limitations on their access to Related Services. Moreover, this is an action for equitable relief from such constraints on Related Services—a systemic remedy that would benefit each member of the NPS Class and subclasses (including the class representatives). Additionally, class counsel is experienced and competent to litigate this matter, a finding that defendants do not dispute.

To contest adequacy, defendants again argue that the proposed class representatives and members have suffered differing harms because the IEP process is too individualized for class-wide resolution. This argument fails for the reasons already stated. Defendants further argue that the class representatives are inadequate because “there are many in the proposed class for whom the [NPS D]irective has caused no harm—either because they now receive [R]elated [S]ervices at their school, they previously received services at their school, or they do not require any [R]elated [S]ervice.” That certain members of the proposed classes may have a diminished interest in the outcome of this litigation does not, however, give rise to a “fundamental” conflict between class representatives and class members as required to defeat adequacy.

e. Ascertainability

Although the NPS Class and subclasses satisfy the express requirements of Rule 23(a), only the NPS Class and Due Process NPS Subclass meet its implied requirement of ascertainability. Accordingly, certification of the Lost Services NPS Subclass is denied.

The NPS Class and Due Process Subclass are ascertainable because they are based on objective, administrable criteria. With respect to the NPS Class, these criteria are whether: a child resides in New York City, has an IEP, and attends or was recommended for an NPS after the alleged NPS Directive was issued. With respect to the Due Process NPS Subclass, these criteria are whether a child receives Related Services and whether the child invokes (or will invoke) due process rights to stay at his or her NPS. Moreover, precise ascertainability is unnecessary, as this is a Rule 23(b)(2) action and no class damages are sought.

Nonetheless, defendants argue that these classes should be found unascertainable because plaintiffs have not adequately defined the terms “NPS Program,” “NPS Directives,” or “[Related] Services.” I find, however, that plaintiffs have adequately defined this terminology (and that defendants’ own materials and testimony suggest that they too understand what these terms mean). Defendants also challenge ascertainability on the basis that the NPS Class and subclass definitions allow for future class members. This argument is a red herring: these future class members cannot, by definition, defeat ascertainability because they will be identified using the same, administrable criteria applicable to current class members. (And, in any event, it is not necessary to identify these people in order to administer injunc-tive relief.)

Unlike the NPS Class and Due Process NPS Subclass, however, the proposed Lost Services NPS Subclass is unas-certainable because it is over-broad. This proposed subclass would cover all individuals who “(i) are members of the NPS Class whose [Related] NPS Services were removed from their IEPs; and (ii) all those who will, in the future, meet the criteria of (i).” Thus, by definition, this subclass would include all students whose Related Services were removed from their IEPs for any reason. The explanation for this expansive subclass definition is obvious: it would be infeasible, if not impossible, to carve out those students whose Related Services were removed for reasons unrelated to the NPS Directive (e.g., because they no longer required Related Services). Further, this subclass is likely unnecessary given that any equitable relief obtained for the NPS Class and Due Process NPS Subclass also will benefit any putative members of the Lost Services NPS Subclass.

2. Proposed Autism Services Class and Subclass

The proposed Autism Services Class and Due Process Autism Subclass also fulfill the requirements of Rule 23(a), with a narrowed class definition as described below.

a. Numerosity

Rule 23(a)(1) numerosity is not disputed and is satisfied for both the Autism Services Class and subclass. With respect to the Autism Services Class, NYSED’s website indicates that, as of October 2014, over thirteen-thousand school-age students in New York City were classified as autistic. Additionally, with respect to the Due Process Autism Subclass, the New York City DOE has represented that 895 autistic students filed for due process hearings during the 2011-2012 school year.

b. Commonality

As explained, plaintiffs seeking class certification must establish, by a preponderance of the credible evidence, that each of Rule 23(a)’s requirements is satisfied, including Rule 23(a)(2)’s commonality requirement that “the class members ‘have suffered the same injury”’ and that their injuries are capable of class-wide resolution. As with the NPS Class and subclasses, defendants argue that the Autism Services Class and subclass lack commonality because plaintiffs have not adequately established that an overarching policy — here, the Autism Services Policies and Practices — binds class members’ claims. Accordingly, defendants argue, plaintiffs’ claims regarding their educational accommodations are too individualized to be capable of common resolution. I find, however, that plaintiffs have established commonality for the Autism Services Class and subclass, subject to certain modifications of plaintiffs’ proposed class definitions.

In seeking class certification, plaintiffs define Autism Services as:

(a) 1:1 instruction with a teacher for all or part of the day; (b) research-based instructional strategies, including, but not limited to, Applied Behavioral Analysis (“ABA”); (c) extended school day, after school or home-based services (for students attending a school-day program); (d) parent training at home; (e) services to promote inclusion; (f) training for staff; (g) rehabilitation training; (h) leisure training; or (i) instruction in a ratio smaller than 6:1:1 for students in a public school.

Accordingly, plaintiffs define Autism Services Policies and Practices — a term that is incorporated into plaintiffs’ definitions of the Autism Services Class and subclass— as “defendants^] restrictions] on the ability of IEP Teams to recommend [the] Autism Services ... on an autistic child’s IEP.”

The class certification record does not, however, support the existence of a blanket policy of denying all of these designated Autism Services at the IEP stage. Rather, the record indicates that certain of these services may be systemically unavailable — namely, (a) one-to-one instruction; (b) ABA; and (c) extended school day, after school, or home-based services. City and State defendants have testified that IEP teams are not permitted to recommend any of these three types of accommodations on IEPs. Further, plaintiffs’ administrative hearing records indicate that defendants made similar representations during IEP meetings and due process hearings. Thus, defendants’ argument that the Autism Services Class and subclass lack commonality because plaintiffs’ claims “are necessarily diverse, distinct, and individualized” fails with respect to ■ one-to-one instruction, ABA, and extended school day, after school, or home-based services. While IEP determinations are necessarily individualized, the record supports finding that defendants have, in fact, adopted a uniform approach with respect to these specific Autism Services.

By contrast, the record does not contain sufficient evidence of a blanket policy regarding the remaining types of accommodations included in plaintiffs’ Autism Services definition. Rather, the eight plaintiffs’ administrative records appear to serve as the only evidence regarding the availability of these services. These discrete due process outcomes — which represent such a small percentage of the proposed class and subclass — are insufficient to create the inference of a blanket approach regarding these additional Autism Services. While it is plausible that the eight plaintiffs’ IEP teams unlawfully denied some or all of these services, this is insufficient to establish the existence of a systemic policy against making such recommendations.

Accordingly, plaintiffs’ definition of Autism Services is modified as follows:

(a) 1:1 instruction with a teacher for all or part of the day; (b) Applied Behavioral Analysis (“ABA”); and (c) extended school day, after school or home-based services (for students attending a school-day program) (the “Modified Autism Services”).

Using this modified definition, I am certifying an Autism Services Class and subclass that are narrowed to address the Autism Services of one-to-one instruction, ABA, and extended school day, after school, or home-based services only. As such, class-wide resolution is appropriate given that the requested relief is limited to an injunction as to certain identified services, which would expand IEP options for all students and not require any individualized inquiry.

c. Typicality

As the Second Circuit has observed, “[t]he commonality and typicality requirements tend to merge into one another.” Accordingly, the Autism Services Class and subclass also fulfill Rule 23(a)(3)’s typicality requirement ‘“that ... each class member’s claim arises from the same course of events’” — here, the Autism Services Practices and Procedures (as modified). As plaintiffs have adequately established the existence of this blanket policy, they have met their typicality burden.

To contest typicality, defendants rehash their position that the “procedures for developing thousands of [IEPs] do not constitute a ‘single course of events’ [because] ... [t]here could be a multitude of reasons underlying the decisions made when developing a student’s program.” As explained, however, the Autism Services Practices and Procedures concern a blanket policy regarding the availability of certain services to the class — ie., a “single course of events” that does not require inquiry into individual IEPs.

d. Adequacy

Further, the proposed class representatives and counsel will “fairly and adequately protect the interests” of the Autism Services Class and subclass. As noted, defendants do not dispute that class counsel is qualified to litigate this action. Further, the proposed class representatives are autistic students who, as a result of the modified Autism Services Policies and Practices, have suffered the harm alleged on behalf of each class member: restrictions on the types of accommodations that their IEP teams are permitted to consider.

Defendants’ sole argument against adequacy is that “the class as defined by Plaintiffs is overbroad, as it must include students who have suffered no harm” because they do not require some or all of the Autism Services. As explained earlier, that some class members may have a diminished interest in the outcome of this suit does not create a “fundamental” conflict between class representatives and members. Notably, the requested relief is a class-wide injunction to expand the universe of IEP options — a remedy that would not, as defendants suggest, interfere with individual IEP determinations or force students to accept Autism Services that they do not want or need.

e. Ascertainability

Finally, the Autism Services Class and subclass also satisfy Rule 23(a)’s implied requirement of ascertainability as both are based on objective criteria. The Autism Services Class will consist of all children who are diagnosed with or classified as autistic, reside in New York City, have an IEP, and have been subject to the modified Autism Services Policies and Practices (which, as alleged, restricts the IEP options of and thus applies to all class members). Further, the Due Process Autism Subclass will consist of all members of the Autism Services Class who win IHO, SRO, court orders, or resolution agreements for the Modified Autism Services. And as with the NPS Class and subclass, precise ascertainability is not required, as this is an action for injunctive, not monetary, relief.

Defendants’ sole argument against as-certainability is mentioned in a footnote which asserts that “the key term ‘Autism Services Policies and Practices’ is left undefined.” As discussed, however, “Autism Services” and “Autism Services Policies and Practices” are defined in the Fourth Amended Complaint. Further, the modified definition of Autism Services set forth in this Opinion narrows the types of accommodations covered by this definition, including limiting the “research-based instructional strategies” to ABA.

B. Rule 23(b)(2)

The surviving classes and subclasses easily satisfy Rule 23(b)(2). Systemic violations like those asserted here present a classic case for Rule 23(b)(2) certification. Echoing their earlier objections, defendants argue that injunctive relief is inappropriate because any such relief would require tailoring to each student’s unique IEP needs. As discussed, however, the relief sought does not require inquiry into individual IEP determinations. Instead, this relief seeks to expand, on a class-wide basis,- the overall menu of IEP options — precisely the type of resolution that Rule 23(b)(2) is suited to provide.

C. The Necessity of Class Certification

Finally, I note that class action is the appropriate vehicle for adjudicating the issues raised by this lawsuit. Absent class certification, thousands of individual students would be required to file for administrative and/or judicial review to assert these concerns. Such review processes are inefficient, burdensome, and available only to those families with the resources to pursue them. Defendants raise several additional arguments against the propriety of class certification, none of which are persuasive.

First, defendants suggest that the Court should “disregard” the allegation that it is difficult to assert procedural rights under the IDEA because “numerous advocacy groups exist” for “parents of lesser means” and the “IDEA’S fee-shifting provision has spawned numerous practitioners who work on something akin to a contingency basis.” Although these options are encouraging, they are not universally available and cannot eliminate the burdens that piecemeal litigation places on families and the court system. And as the City Defendants themselves have conceded, administrative officers are “not ... empowered to resolve this sort of system-wide claim.”

Second, defendants argue that certification should be denied because “there is a system in place” to seek administrative review of the issues raised by this lawsuit. As discussed, however, the administrative process is neither readily accessible to all families nor an efficient avenue for addressing systemic claims..

Third, defendants suggest that class certification is unnecessary because any judgment for plaintiffs would spur defendants to apply that favorable determination to all similarly-situated students. Although the Second Circuit has found (b)(2) certification unnecessary where a defendant “represented” that it “had no intention of reinstating” a challenged policy, defendants have made no such representations here. Although it is probable that defendants would alter their policies after receiving an unfavorable judgment, a defendant’s representations must be “express,” or otherwise “explicit,” before class certification may be denied on this basis. And it is nonetheless possible that defendants could respond to an adverse judgment by changing some, but not all, unlawful aspects of their decision-making. Thus, to accept this argument would deeply undervalue the class action, a mechanism that has proved so important in addressing defects within the public education system.

Y. CONCLUSION

For the foregoing reasons, plaintiffs’ motion for class certification, appointment as class representatives, and approval of class counsel is GRANTED in part and DENIED in part. Class certification is (1) granted in full for the NPS Class and Due Process NPS Subclass; (2) denied for the Lost Services NPS Subclass; (3) and granted, as modified herein, for the Autism Services Class and Due Process Autism Subclass. For the surviving classes and subclasses, plaintiffs’ request for appointment as class representatives and approval of class counsel is granted.

The Clerk of the Court is directed to close this motion (Dkt. No. 92). A conference is scheduled for January 15, 2016 at 3:30 PM.

Although the State and City Defendants both argue against class certification of the NPS and Autism Services classes, the State Defendants’ opposition brief focuses on the NPS Class whereas the City Defendants' opposition brief focuses on the Autism Services Class.

      . City Def. Opp. at 8. Defendants also suggest that there can be no policy against providing these services because NYSED "has promulgated regulations ‘to specifically ensure that students with autism services receive the services and programs required.’” State Def. Opp. at 24 (quoting 8 N.Y.C.R.R. § 200.13(c)). This argument is unpersuasive, as it does not contradict the record evidence that certain services are systemically unavailable at the IEP stage. Moreover, that defendants' policies against designating one-to-one instruction, ABA, or extended school day, after school, or home-based services on IEPs may comport with educational regulations is a merits question that is not intertwined with the commonality analysis. Further, defendants’ renewed argument that plaintiffs have failed to meet their commonality burden because they have not submitted affidavits, expert reports, or statistical analysis also fails because, as discussed, there is sufficient evidence elsewhere in the record regarding restrictions on including certain services on IEPs. See id. at 23.
     
      
      . These services are: (d) parent training at home; (e) services to promote inclusion; (f) training for staff; (g) rehabilitation training; (h) leisure training; or (i) instruction in a ratio smaller than 6:1:1 for students in a public school.
