Lead Opinion
Under the Individuals with Disabilities Education Act and its implementing regulations, parents who disagree with a school district’s evaluation of their child may be entitled to an independent educational evaluation (IEE) at public expense. The parents of Seth B., a child who had previously been diagnosed with autism, asked the Orleans Parish School Board for such an evaluation. After the board assented, Seth’s parents obtained the IEE and sought reimbursement. The school board denied their request on the ground that the IEE did not conform to state criteria. A state administrative hearing officer and the district court subsequently ruled that reimbursement was not warranted. We vacate and remand.
I
The Individuals with Disabilities Education Act (IDEA) seeks “to ensure that all children with disabilities have available to them a free appropriate public education.”
Seth B. attended public school in New Orleans. He had been diagnosed with autism and was identified as a child with a disability under IDEA. In August 2011, Seth’s parents sent the Orleans Parish School Board (OPSB) a request for an IEE. The board granted the request, offering reimbursement up to $3,000 on condition that the IEE comply with Louisiana Bulletin 1508.
After some correspondence with the board concerning the $3,000 cost cap, Seth’s parents engaged Dr. Patricia Brock-man to produce Seth’s IEE. In April 2012, they sent OPSB Dr. Brockman’s report. OPSB responded the next month with a letter outlining 31 ways in which the IEE allegedly did not meet Bulletin 1508 criteria. The board invited Seth’s parents to have Dr. Brockman contact them to discuss the alleged areas of noncompliance. The parents did not reply to this letter, and there is no indication that Dr. Brock-man ever contacted the board. However, Seth’s IEE was discussed in an administrative hearing, ongoing at this time, concerning whether Seth was receiving a free appropriate public education.
On December 26, 2012, several months after OPSB sent its objections, Seth’s parents sent the board invoices from the IEE totaling $8066.50 and requested reimbursement. The board allegedly did not receive the request until January 31, 2013. On February 28, it denied the request in a letter to Seth’s parents, noting that it could not reimburse them for a noncompli-ant evaluation and that some of the invoices appeared unrelated to the completion of the IEE.
In April 2013, Seth and his parents requested an administrative due process hearing.
Seth and his parents sought review in federal district court pursuant to the IDEA.
This appeal followed. The Council of Parent Attorneys and Advocates, Inc., the National Disability Rights Network, the National Federation of the Blind, and the National Association of the Deaf filed ami-cus briefs urging reversal. The National School Boards Association, the National Association of State Directors of Special Education, and school board associations from Louisiana, Mississippi, and Texas filed an amicus brief urging affirmance.
II
Under 20 U.S.C. § 1415(i)(2)(C), which formed the basis for this action, a district court must (i) “receive the records of the administrative proceedings”; (ii) “hear additional evidence at the request of a party”; and (iii) base “its decision on the preponderance of the evidence” and “grant such relief as the court determines is appropriate.” The district court is required to “accord ‘due weight’ to the hearing officer’s findings,” but it “must ultimately reach an independent decision based on the preponderance of the evidence.”
We have never articulated the standard of review for the appeal of a district court’s determination that an IEE does not merit reimbursement. Plainly, however, the district court’s inquiry was one of both fact and law, in that the court both interpreted the requirements of federal and state educational regulations and analyzed whether appellants’ IEE and the board’s conduct conformed to those requirements. “Mixed questions should be reviewed under the clearly erroneous standard if factual questions predominate, and de novo if the legal questions predominate.”
Ill
We first consider whether OPSB waived its right to refuse reimbursement. Appellants and amici contend that it did, both because the board failed to initiate a hearing to contest Seth’s IEE and because it unnecessarily delayed in complying with its duties under IDEA’S implementing regulations. We disagree.
1. Initiation of the due process hearing
Disputes over IEE reimbursement are governed by an implementing regulation of the IDEA, 34 C.F.R. § 300.502, which reads in relevant part:
(b) Parent right to evaluation at public expense.
[•••]
(2) If a parent requests an independent educational evaluation at public expense, the public agency must, without unnecessary delay, either—
*968 (i) File a due process complaint to request a hearing to show that its evaluation is appropriate; or
(ii) Ensure that an independent educational evaluation is provided at public expense, unless the agency demonstrates in a hearing pursuant to §§ 300.507 through 300.513 that the evaluation obtained by the parent did not meet agency criteria.14
In this case, after appellants requested an IEE at public expense, OPSB neither requested a hearing to show that its own evaluation was appropriate, nor did it request a hearing to show that appellants’ evaluation failed to meet relevant criteria. Rather, appellants requested a hearing on the subject of reimbursement. They now claim that the regulation required OPSB to request a hearing, and that by failing to do so, the board waived its right to refuse reimbursement.
The plain text of the regulation contradicts appellants’ reading. § 300.502(b)(2)(h) excuses an agency from paying for an IEE if the agency simply “demonstrates in a hearing ... that the evaluation obtained by the parent did not meet agency criteria.”
Appellants and amici. refer us to Department of Education commentaries suggesting that § 300.502(b)(2)(ii) gives a school district the duty to initiate a hearing in this context. This contradicts the unambiguous text of the regulation. “If [a] regulation is unambiguous, we may ... consider agency interpretation, but only according to its persuasive power.”
Appellants and amici also cite several out-of-circuit cases in support of their reading of § 300.502(b)(2)(ii). We find these cases unpersuasive. In Evans v. District No. 17, the Eighth Circuit required a school district to reimburse parents for the cost of their IEE because the district never “initiated a hearing ... to show the inappropriateness of the [parents’] evaluation, or to show that its evaluation [was] appropriate.”
In sum, neither the plain text of the regulation nor binding precedent required OPSB to initiate a hearing in order to contest appellants’ right to'reimbursement. This result conforms with the broader purpose of § 300.502(b), that is, to ensure parents’ rights to an IEE at public expense and to due process in the event of a reimbursement dispute. These rights can be vindicated just as well in a hearing initiated by the parents as in one initiated by a school district, as the Sixth Circuit recognized in P.R. v. Woodmore Local School District.
As long as the object of the regulations is accomplished, there is no reason to exalt form over substance. Their purpose is not served by holding that there must be reimbursement at public expense when it is the parents rather than the public agency that initiates the due process hearing where the appropriateness of the School District’s Evaluation is challenged and confirmed.27
The Sixth Circuit’s insight applies with even greater force in the context of § 300.502(b)(2)(ii), whose plain text — unlike that of (b)(2)(i) — does not require the agency to initiate a hearing.
2. Timeliness
OPSB did not have to initiate a hearing in order to preserve its objection to Seth’s IEE. This is not to say, however, that the board could wait indefinitely, forcing appellants to either demand a hearing or forsake reimbursement. Rather, under § 300.502(b)(2)(ii), OPSB had to “demonstrate” the IEE’s noncompliance with relevant criteria “without unnecessary delay.” We find that OPSB fulfilled this duty.
Appellants sent the board an e-mail on August 25, 2011, stating that “we are requesting an Independent Educational Evaluation for our son Seth____ Seth is entitled to receive a comprehensive IEE at public expense.” However, the record indicates that appellants did not submit invoices until over a year later. Only then could OPSB know with certainty that appellants sought an IEE at public expense
Appellants’ invoices accompanied a letter dated December 26, 2012, which OPSB claims it did not receive until January 81, 2013.
At the outset, we observe that there is little case law or regulatory guidance speaking directly to this question. Appellants and amici cite numerous rulings of lower courts and state agencies, but most of these rulings appear to involve school districts failing to timely respond to parents’ initial requests for IEEs “without unnecessary delay.” Thus, in many of the cited cases, upon receiving a parent’s IEE request, the school district took no action — neither granting the request, nor filing for a due process hearing to demonstrate the adequacy of their own evaluation.
These cases provide limited guidance in the case before us, in which the board delayed not in responding to or challenging parents’ initial IEE inquiry, but in contesting their right to reimbursement after the IEE had been completed.
To be sure, keeping parents waiting for three or four months before action is taken on reimbursement may be a significant burden, considering the cost of IEEs. But such a delay does not have the same effect (or even any effect) on a child’s educational plan as failing to take action on an initial request for an IEE does. Here, any delay by OPSB did not affect whether the IEE could be considered in relation to Seth’s schooling plan.
IV
We next consider whether appellants were denied their procedural rights in the district court proceeding. Appellants contend that the district court improperly placed the burden of persuasion on them. The district court reasoned that “the burden of persuasion [should] fall[] where it usually does, on the party seeking relief.” Appellants argue that the typical presumption should not apply in IEE reimbursement disputes, since 34 C.F.R. § 300.502(b)(2)(h) requires the agency, not the parents, to “demonstrate” noncompliance with relevant criteria. However, this requirement applies only to administrative due process hearings.
V
Having determined that OPSB did not waive its right to refuse reimbursement and that the proceedings before the district court were procedurally sound, we approach the crux of this dispute: whether appellants’ IEE failed to “meet agency criteria,” precluding reimbursement.
First, appellants contend that OPSB may only apply criteria “employed at the initiation of an evaluation,” and not “eon-tent-based” criteria. They cite 34 C.F.R. § 300.502(e)(1), which provides that “[i]f an independent educational evaluation is at public expense, the criteria under which the evaluation is obtained, including the location of the evaluation and the qualifications of the examiner, must be the same as the criteria that the public agency uses
Appellants do not explain how to distinguish “initiation” criteria from “content-based” criteria. Moreover, the phrase “when it [i.e., the agency] initiates an evaluation” could plausibly be understood to identify the evaluations relevant to determining criteria applicable to IEEs, not to limit those criteria. In other words, the regulation can be read to simply subject IEEs (i.e., evaluations initiated by parents) to the same criteria as agencies’ own evaluations (i.e., evaluations initiated by agencies). Nonetheless, appellants’ reading— that the phrase is language of limitation, not identification — is also plausible as a purely textual matter.
When confronted with ambiguity in regulatory text, we look to agency interpretations.
We do not believe it is necessary to add language to the regulations regarding the review of existing data, input from the child’s parents, the scope of the evaluation, or the instruments used to evaluate the child, because an IEE must meet the agency criteria that the public agency uses when it initiates an evaluation. ... Similarly, [the IDEA regulations] provide!] that an evaluation conducted by a public agency must use a variety of assessment tools and strategies to gather relevant functional, developmental, and academic information about the child, including information provided by the parent, that may assist in determining whether the child is a child with a disability.... These requirements also apply to an IEE conducted by an independent evaluator, since these requirements mil be a part of the agency’s criteria,49
This interpretation is consistent with IDEA’S underlying purposes.
Second, appellants appear to argue that Bulletin 1508’s criteria, including those that require a multidisciplinary team, are generally inapplicable to an IEE because that document is oriented toward schools and does not address IEEs in detail.
Third, appellants claim that only the portions of the IEE relating to their areas of disagreement with the board had to comply with Bulletin 1508 criteria. They invoke DOE guidance allowing an IEE to be limited to the scope of disagreement between parents and an agency. Perhaps, but this guidance does not directly address reimbursement.
Fourth, appellants claim that Seth’s IEE was a reevaluation, not an initial evaluation, and that initial evaluation criteria are therefore inapplicable. In
Fifth, and finally, running through appellants’ briefs is the underlying contention that Bulletin 1508 is so onerous as to cumulatively and inherently violate parents’ right to an IEE.
We do not doubt that Bulletin 1508 imposed a heavy burden in this case. In
VI
The Bulletin 1508 criteria implicated in OPSB’s 31 alleged areas of noncompliance apply to Seth’s IEE. We may therefore consider whether the IEE complies with those criteria. As we have noted, the ALJ below resolved this question against appellants, apparently on the basis of an alleged stipulation as to the IEE’s noncompliance. Appellants deny that they so stipulated, and the record is ambiguous as to this point.
The district court upheld the ALJ’s noncompliance finding. It did not address appellants’ argument that the IEE was substantially compliant. Rather, citing the ALJ’s finding and OPSB’s recital of the 31 alleged areas of noncompliance, it simply held that “the parties agree that the IEE obtained by Plaintiffs does not meet Bulletin 1508 criteria” and that “Plaintiffs are not entitled to reimbursement because the IEE at issue does not comply with Bulletin 1508 criteria.”
The degree of compliance necessary for an IEE to “meet agency criteria” under 34 C.F.R. § 300.502 is not explicitly defined in IDEA, its implementing regulations, or the case law, nor is there any directly relevant agency guidance. Yet standards akin to substantial compliance are already deployed in other IDEA contexts.
We are persuaded that substantial compliance also suffices in the IEE context. 34 C.F.R. § 300.502 nowhere demands perfect adherence to agency criteria.
As the Supreme Court has emphasized, IDEA’S procedural safeguards, including the right to an IEE, are essential to the statutory scheme.
A substantial compliance standard for IEE reimbursement also advances these purposes. First, it safeguards parents’ ability to participate in the IDEA process through IEEs by preserving a realistic possibility of reimbursement. The state criteria that govern IDEA evaluations can be complex. Given this, and given their “natural advantage in information and expertise” in this context,
The board worries that “[i]f this Court were to adopt the Plaintiffs’ implicit criterion of “substantial” compliance____ [b]ased on an unreasonably low standard, presumptively a couple of paragraphs — or even a prescription pad with ‘OHI,’ ‘Autism,’ or ‘SLD’ with little more — would suffice as an IEE.” Although the slippery slope is always a concern when the law accepts less-than-perfect compliance,
In so holding, we are mindful of our limited expertise.
VII
Seth’s IEE will “meet agency criteria” and merit reimbursement if it substantially complies with Bulletin 1508. As noted above, the district court did not squarely address this factually specific question. We therefore remand for analysis under a substantial compliance standard. If the court below (or, upon further remand, the administrative hearing officer) finds the IEE substantially compliant, it should award reimbursement.
In any event, however, appellants will not be entitled to the full cost of the evaluation they obtained. Appellants knew of OPSB’s $3,000 cost cap for IEEs, yet they spent over $8,000. The Department of Education has explained that IDEA allows schools to enforce reasonable cost criteria for IEEs as long as parents in unique circumstances have the opportunity to request exemption.
We VACATE and REMAND to the district court for further proceedings consistent with this opinion.

Petitioners also refer to a comment accompanying the 1999 issuance of revised IDEA regulations, to the effect that school agencies must either initiate a due process hearing or provide an IEE at public expense.

See id. (“The purpose of requiring the public agency to'either initiate a due process hearing if it wishes to challenge a parent’s request for an IEE, or otherwise provide an IEE at public expense, is to require public agencies to respond to IEE requests....

Rather, the regulation makes clear that the right to reimbursement pertains to the IEE as a whole, not to its subparts. Therefore, the IEE as a whole must meet agency criteria in order to merit reimbursement.

However, it is unclear from the facts provided in Norwalk whether (a) the Board's "methodological” concerns in that case were rooted in Board criteria that were not “initiating” criteria, or (b) whether the Board’s "methodological” concerns had no origin in Board criteria of any sort.

With regard to the multidisciplinary team requirement specifically, petitioners argue that the use of the singular “examiner” in 34 C.F.R. § 300.502(a)(3)(i), which defines an IEE as “an evaluation conducted by a qualified examiner who is not employed by the public agency responsible for the education of the child in question,” indicates that IEEs need not involve multiple specialists. It is a basic rule of statutory construction that the singular includes the plural. See Antonin Sca-lia & Bryan A. Garner, Reading Law: The Interpretation of Legal Texts 130 (2012) (quoting the rules of construction outlined in 1 U.S.C. § 1). Thus, the fact that “examiner” is singular is hardly dispositive.

. If petitioners agreed with some elements of the school's evaluation, it would seem more appropriate for them to have not tested those areas in the first place, rather than testing them (allegedly) inadequately and then disputing reimbursement. Petitioners would surely respond that they only tested in areas of agreement because OPSB made them. Yet if their complaint is that the school district required them to have a comprehensive IEE, then they should have disputed this prior to obtaining one. Now that they have, the IEE must comply with applicable criteria to merit reimbursement.

. In particular, Seth’s family was unwilling to use one of OPSB’s two recommended providers because that provider employed Seth's father, requiring a broader search and closing off a potentially inexpensive option closer to home. Petitioners also appear to have suffered unexpected setbacks once they found providers, including one evaluator's unexpected health and administrative problems and another’s unwillingness to make needed revisions to the evaluation. Finally, Seth’s IEE happens to be subject to extensive initial evaluation criteria because Seth’s parents suspected an additional exceptionality.

. Bulletin 1508 consists of 35 dense pages of detailed directives. When OPSB approved Seth's parents’ request for an IEE, its employee essentially just sent them a copy of the Bulletin with instructions to stick to it.
. The board alternatively contends that it "demonstrated” the IEE's noncompliance at the 2012 due process hearing between the parties, which preceded the AU's ruling. We disagree. The purpose of that hearing was to determine whether Seth was receiving FAPE, not whether the IEE merited reimbursement. Although the IEE appears to have been extensively discussed at the hearing, the record lacks any evidence that the ALJ decided whether the IEE actually met agency criteria. Without such a determination, we cannot say that OPSB "demonstrated” the IEE’s deficiency in 2012.

Dissenting Opinion
dissenting.
The majority’s creation — from whole cloth — of a substantial-compliance standard in Part VI is a dramatic judicial amendment of the Individuals with Disabilities Education Act (“IDEA”) without textual or precedential justification. It is both a usurpation of regulatory authority and an invitation for courts to engage in arbitrary decisionmaking. And, the majority provides scant direction on what substantial compliance really means. I respectfully dissent.
I.
Though my colleagues observe that this court has used a substantial-compliance standard in other applications of the IDEA, those cases involved a distinct statutory basis. All of the cases cited by the majority relate to whether a school’s alleged failure to develop or implement an individualized education plan (“IEP”) deprived students of a free and appropriate public education (“FAPE”).
Title 34 C.F.R. § 300.502(e)(1) has a plain textual mandate: The criteria under which an IEE is obtained at public expense “must be the same as the criteria that the public agency uses when it initiates an evaluation.” (Emphasis added.) And if the agency (the school) demonstrates that “the evaluation obtained by the parent did not meet agency criteria,” it need not pay for it. 34 C.F.R. § 300.502(b)(2)(h) (emphasis added). There is no qualifying language such as “substantially” or “mostly.”
In contrast, where courts have applied a “substantial compliance” standard to determine whether a school denied a student a FAPE in its development of or implementation of an IEP, the IDEA is less specific. “It is well-settléd that, without a claim that the FAPE was deficient, procedural defects are not actionable.” T.S., 265 F.3d at 1095; see also Adam J., 328 F.3d at 812 & n. 23 (adopting the approach in T.S.). Thus, to assert that a school failed to follow IDEA regulations regarding an IEP, the claimant must make an overall allegation that a FAPE itself was denied.
The IDEA does not prescribe substantive standards for what constitutes a FAPE. As explained in Board of Education v. Rowley, 458 U.S. 176, 205, 102 S.Ct. 3034, 73 L.Ed.2d 690 (1982),
Procedural defects alone do not necessarily result in lost educational opportunities. Therefore, given the lack of guidance in the IDEA regarding the substance of a FAPE, and, thus, what an IEP is supposed to achieve, it is not surprising that in that context courts employ a “substantial-compliance” standard and excuse minimal procedural violations. See, e.g., id
Instead, there is good reason for schools to be required to pay only for those IEEs that fully comply with state evaluation criteria, as the majority comes close to acknowledging.
II.
The majority’s decision to apply a “substantial-compliance” standard is in tension with its earlier holding, in the last portion of Part V, that the IEE must comply with Bulletin 1508’s criteria. Implicit in the parents’ claim that they need only “substantially comply” with Bulletin 1508’s requirements is a contention that they can flout (or fail to comply with) some of Bulletin 1508’s criteria. Yet, if parents can ignore some of the criteria,.to what extent do they need to comply with Bulletin 1508 at all?
The majority provides meager guidance to the district courts on what “substantial compliance” looks like in the context of IEE reimbursement. Is meeting six out of ten criteria enough, or does it matter what kind of criteria are at issue? According to my colleagues, “[sjubstantial compli-anee ... means that insignificant or trivial deviations from the letter of agency criteria may be acceptable as long as there is substantive compliance with all material provisions of the agency criteria....”
That definition collapses on itself. Substantial compliance is “substantive compliance.” What is material and what is insignificant? The majority offers little indication. Instead, this so-called “standard” asks judges to act as policymakers to determine which agency criteria are and are not important.
Apparently, “substantial compliance” also requires the IEE to “provide[] detailed, rigorously produced and accessibly presented data.” Yet, data can be detailed, rigorously produced, and accessibly presented and still not be useful if it measures the wrong types of abilities. Thorough methodology does not compensate for categorical errors. That part of the definition is also unhelpful.
At this point, there is no way to know what constitutes substantial compliance; instead, that term sends a nod to district courts that “you will know it when you see it.” That is a standardless and, for the most part, useless pronouncement that lends itself to abuse. In contrast, a bright-line rule, requiring an IEE to comply with all agency criteria in order to be reimbursed, is much easier to administer and removes boundless discretion from the district courts.
III.
The school board articulated thirty-one ways in which Seth’s IEE failed to comply with state criteria, in addition to its failure
This conclusion is further strengthened if we look beyond the arguments and examine the record submitted to the district court.
For example, the IEE did not contain a description of Seth’s educational needs in prioritized order.
Although the IEE contained plenty of data regarding Seth’s overall abilities, and it did make recommendations for future improvement, there was little analysis of past performance and accommodations. The effectiveness of current and prior learning strategies, however, is an important data point in planning future interventions. Therefore, even if some of the areas of non-compliance were minor, there is no doubt that the IEE failed to comply with Bulletin 1508 in significant ways. Thus, even if we purport to apply a substantial-compliance standard, the IEE is fatally non-compliant.
IV.
The majority contends that absent a substantial-compliance standard,' schools will treat IEE reimbursement “as a privilege to be granted at their discretion” and thus effectively deny parents’ right to an IEE, undermining the purposes of the Act.
In this court, the parents challenge some of the requirements in Bulletin 1508 as infringing their right to an IEE, including the imposition of content-based criteria, the necessity of a multidisciplinary team, and applying the criteria for initial evaluations as opposed to reevaluation criteria.
V.
The majority’s decision to impose a judge-made standard on IEE reimbursements is deeply flawed. The majority cites not one single word in the IDEA or its accompanying regulations that points to the existence of a substantial-compliance standard for IEE reimbursement.
That is not to say that purpose is irrelevant-, but it is operationalized via the text. See Scalia & Garner, supra, at 20 (explaining that textualism “routinely takes purpose into account, but in its concrete manifestations as deduced from a close reading of the text”). The danger arises when purpose is disembodied from the text. Indeed, “[t]he most destructive (and most alluring) feature of purposivism is its pure manipulability.” Id. at 112-15. “Any provision of law or of private ordering can be said to have a number of purposes, which can be placed on a ladder of abstraction.” Id. Law then becomes whatever the judges wish it to be.
The majority opinion not only serves as an example of such personal-preference decisionmaking but also provides little direction to district courts on how its new extra-textual standard operates. Instead, the majority invites the district judges to engage in the same sort of judicial arbitrariness, as they apply their own notions to decide what is and is not substantially compliant. Not only is such purposivism inappropriate, it is unnecessary. As I have explained, if the concern is that parents will be prohibited .from obtaining IEEs, the regulations already provide an avenue for them to challenge the imposition of overly burdensome criteria.
Judges must resist the siren call to become lawmakers. I respectfully dissent.
. Rowley is the case often cited by courts in discussing the substantial-compliance standard. See, e.g., Bobby R., 200 F.3d at 346, 349; Van Duyn, 502 F.3d at 821-22; Clark, 315 F.3d at 1027 & n. 3.
. Although determining whether a FAPE has been provided is a completely different inquiry from determining whether an IEE is eligible for public reimbursement, 20 U.S.C. § 1401(9)(D) does explain that a FAPE is "provided in conformity with the [IEP].” Thus, there is some textual basis for requiring schools, in order to provide a FAPE, to comply with all of the procedural requirements governing IEPs. Some of the critiques I make here of a substantial-compliance standard for IEE reimbursements could apply to a substantial-compliance standard in the context of FAPE violations. Yet, though the substantial-compliance standard for FAPE violations is the established rule in this circuit, see Adam J., 328 F.3d at 812, there is no Fifth Circuit precedent on the requirements for IEE reimbursement.
. "Allowing parents to ignore Bulletin 1508’s criteria can complicate subsequent efforts to compare the IEEs to the districts’ own evaluations, undermining a key function of the IEE.”
. See, e.g., 34 C.F.R. § 300.304(b)-(c) (outlining requirements for school-conducted evaluations).
. According to the majority, the district court “simply held ... that ‘Plaintiffs are not entitled to reimbursement because the IEE at issue does not comply with Bulletin 1508 criteria.’ ” Thus, the majority implies that the court accepted the school board's allegations without conducting further analysis. That is a mischaracterization of the opinion, whose entire sentence reads, "Plaintiffs are not entitled to reimbursement because the IEE at issue does not comply with Bulletin 1508 criteria with respect to the four areas of testing above." (Emphasis added.) Though the district court's analysis was somewhat limited, it did address each of these four areas of noncompliance.
. Indeed, the parents earlier admitted that the IEE did "not contain some elements or components required by Bulletin 1508 criteria.” Nevertheless, the parents briefly did reference a chart submitted to the district court in which they disputed the thirty-one counts of non-compliance. Yet they did not elaborate on those arguments in their submissions before us. Failure adequately to brief an issue on appeal is waiver. See Fed. R.App. P. 28(a)(8)(A); United States v. Beaumont, 972 F.2d 553, 563 (5th Cir.1992).
. Absent adequate argumentation in a brief, we are not required to comb through the record to look for points presented in the district court. Beaumont, 972 F.2d at 563. Nonetheless, I have conducted additional, albeit limited, analysis of the thirty-one areas of alleged non-compliance, and my findings are summarized above.
. The parents contend that any failure to follow Bulletin 1508 was inconsequential. Thus, although acknowledging that the IEE was missing some components, they contended that the IEE "substantially” complied with Bulletin 1508's criteria. It is true that some of the thirty-one areas of non-compliance appear less significant and probably would have been easy to correct. For example, the IEE did not provide Seth’s achievement scores using chronological age norms; instead, it used grade-based norms. Nevertheless, even though the school board offered to provide guidance to help the parents bring the IEE into full compliance, the parents failed to do so.
. In the district court, the parents noted that the school board had not included a prioritized list of educational needs in its previous evaluations. Even if the parents are correct, “two wrongs don’t make a right.” Bulletin 1508 states that a prioritized list is required. See Bulletin 1508, La. Admin. Code tit. 28, pt. Cl at § 513(B)(1)(g) (2009). Indeed, if the school did fail to include such a list in prior evaluations, there was even more reason for the IEE to include it, because IEEs frequently are designed to supplement school-board assessments.
. The physical-therapy evaluation did assess Seth’s overall gross motor skills, as the parents note, but there is no indication that the physical therapist evaluated Seth in an educational environment, as Bulletin 1508 requires. See La. Admin. Code tit. 28, pt. Cl § 1507(C)(l)(b)(i).
. Interventions are learning strategies that are tailored to individual students’ specific needs. See, e.g., Bulletin 1508, La. Admin. Code tit. 28, pt. Cl, § 301. Bulletin 1508 requires evaluations to contain an analysis of existing interventions. See id. § 513(B)(1)(c).
. The IEE states that documentation of evidence-based interventions was not provided as part of Seth’s educational records. Nevertheless, the IEE later refers to teachers who mentioned interventions and to accommodations that were based on a 2010 evaluation of Seth conducted by the school, so its failure to analyze at least these interventions more fully is inexplicable. The IEE also mentions IEP progress reports, so its earlier statement that there was no documentation from the school regarding Seth’s performance is contradictory.
. The majority’s reliance on purposivism is misguided. See infra Part V.
. Though the parents challenged the application of more specific criteria in the district court, they do not press those challenges before us, so they Eire waived.
. Indeed, the majority observes, "The degree of compliance necessary for an IEE to ‘meet agency criteria' under 34 C.F.R. § 300.502 is not explicitly defined in IDEA, its implementing regulations, or the case law, nor is there any directly relevant agency guidance.”
. The majority’s flawed approach is encapsulated in its footnote urging us to interpret ambiguous statutes according to their purpose. This misses the point that in regard to whether IEEs must meet all agency criteria, there is no ambiguity. In the absence of language to the contrary, the plain implication of the text is that IEEs need to comply fully with local regulatory requirements. The regulatory drafters did not say that IEEs "may be required” to comply with agency criteria; instead they stated that IEEs “must” comply. 34 C.F.R. § 300.502(e)(1); see also Antonin Scalia & Bryan A. Garner, Reading Law: The Interpretation of Legal Texts 112-15 (2012) (explaining that "[mjandatory words,” such as "must” "impose a duty,” and "permissive words grant discretion”).
Thus, by the majority’s own reasoning there is no need to surmise regulatory purpose, because there is no ambiguity. Even if there were, the proper approach would be to use the various textual canons of statutory interpretation to resolve any textual uncertainties. See, e.g., POM Wonderful LLC v. Coca-Cola Co., - U.S. -, 134 S.Ct. 2228, 2236, 189 L.Ed.2d 141 (2014) (applying textual canons and explaining that "[a]nalysis of the statutory text, aided by established principles of interpretation, controls").
