Special Education Law: IDEA, IEPs, Section 504, and Parent Rights

Summary. This article explains what a free appropriate public education requires after Endrew F., how child find and evaluation work, what an IEP must contain, how it differs from a Section 504 plan, what least restrictive environment requires, the procedural safeguards that give the statute its force, how disciplinary removals work, and the dispute paths from a facilitated meeting into federal court.

There is a particular sentence parents hear in IEP meetings, and it is almost always wrong: "We don't do that here."

Sometimes it means the district does not offer a service. Sometimes it means the person saying it does not know the district offers it. Almost never does it mean what it sounds like it means — that the law permits the district to decline. Because the Individuals with Disabilities Education Act is not, at bottom, a statute about educational methods. It is a procedural statute, and its central insight is that a parent armed with the right to be present, to be informed, to disagree in writing, and to be heard by a neutral decisionmaker will produce better outcomes than any substantive standard a legislature could write.

That is why the safeguards in Part VI of this article matter more than the standards in Part II, and why the parents who do best are not the ones who know the most about reading instruction. They are the ones who write things down.

Part I: The two statutes, and how they differ

IDEA — the Individuals with Disabilities Education Act, 20 U.S.C. § 1400 et seq. — is a funding statute with conditions. States that accept federal special education funds must, under 20 U.S.C. § 1412, make a free appropriate public education available to every child with a disability in the least restrictive appropriate environment, with the full apparatus of evaluation, IEPs, and procedural safeguards. Its implementing regulations are at 34 C.F.R. Part 300.

Section 504 of the Rehabilitation Act, 29 U.S.C. § 794, is a civil rights statute: no otherwise qualified individual with a disability shall, solely by reason of the disability, be excluded from participation in, denied the benefits of, or subjected to discrimination under any program receiving federal financial assistance. It reaches every public school, and it applies to a much broader population.

The practical differences:

Two consequences follow. First, a child who does not qualify under IDEA may still qualify under 504 — a child with ADHD, diabetes, anxiety, or a food allergy who needs accommodations but not specially designed instruction is the classic case. Second, every child with an IEP is also protected by 504, and by the ADA, which matters when the dispute is about discrimination rather than about services.

Part II: What FAPE requires — from Rowley to Endrew F.

The statutory phrase is "free appropriate public education," and for thirty-five years its meaning came from one case.

Board of Education v. Rowley, 458 U.S. 176 (1982) held that the statute does not require a school to maximize a child's potential. It requires an IEP "reasonably calculated to enable the child to receive educational benefits." Some lower courts read that language to require only benefit that was more than de minimis — a standard under which a child could receive a legally adequate education while making almost no progress.

Endrew F. v. Douglas County School District RE-1, 580 U.S. 386 (2017) rejected that reading unanimously. Chief Justice Roberts wrote that a school must offer an IEP "reasonably calculated to enable a child to make progress appropriate in light of the child's circumstances," and — in the sentence that has been quoted in every hearing since — that a standard requiring merely more than de minimis progress "would be tantamount to 'sitting idly . . . awaiting the time when they were old enough to drop out.'"

What Endrew F. actually changed:

• The IEP must be appropriately ambitious in light of the child's circumstances, and every child should have the chance to meet challenging objectives.
• For a child fully integrated in the regular classroom, an IEP reasonably calculated to enable grade-level advancement is generally required.
• For a child not fully integrated, the IEP need not aim for grade-level advancement, but the goals must be appropriately ambitious — not merely "barely more than nothing."
• The district must be able to offer a cogent and responsive explanation for its decisions, showing the program is reasonably calculated to enable progress.

That last point is the practically important one. Endrew F. is, in operation, a reasoned-explanation requirement, and the question that decides most modern cases is whether the district can explain, with data, why this program was expected to produce this progress for this child.

Part III: Child find and evaluation

The child find duty. 20 U.S.C. § 1412(a)(3) requires states and districts to identify, locate, and evaluate all children with disabilities residing in the state who are in need of special education — including children in private schools, homeless children, and children who are advancing from grade to grade. The duty is affirmative: it is triggered by suspicion of a disability, not by a parent's request, and a district that has data suggesting a disability and does nothing has violated it.

Requesting an evaluation. A parent may request one in writing at any time. The request starts the clock. Under 20 U.S.C. § 1414, the evaluation must be completed within 60 days of receiving parental consent (or a shorter state timeline), must use a variety of assessment tools, must not rely on any single measure, and must assess in all areas of suspected disability.

If the district refuses, it must give prior written notice explaining the refusal and the data it relied on. That notice is a gift: it commits the district to a written rationale that can be tested, and it triggers the parent's right to challenge the refusal through a complaint, mediation, or a due process hearing.

Response to intervention is not a permissible delay. A district may use RTI or MTSS, but it may not use them to postpone an evaluation once a disability is suspected. This is the most common child find violation in practice.

Independent educational evaluations. If a parent disagrees with the district's evaluation, they have the right to an IEE at public expense. The district must either fund it or, without unnecessary delay, file for a due process hearing to defend its own evaluation. It may impose reasonable cost criteria, but it may not simply refuse. The district must consider an IEE the parent obtains privately, whoever paid for it.

Part IV: The IEP

20 U.S.C. § 1414(d) specifies what an IEP must contain:

1. Present levels of academic achievement and functional performance, including how the disability affects involvement and progress in the general curriculum.
2. Measurable annual goals — academic and functional — designed to meet the needs resulting from the disability and to enable involvement in the general curriculum.
3. How progress will be measured and when reports will be provided.
4. The special education, related services, and supplementary aids and services to be provided, and program modifications and supports for school personnel — all based on peer-reviewed research to the extent practicable.
5. An explanation of the extent, if any, to which the child will not participate with nondisabled children in the regular class and activities.
6. Accommodations for assessments, and if an alternate assessment is used, why.
7. The projected start date, frequency, location, and duration of services.
8. Transition services beginning not later than the first IEP in effect when the child turns 16 (earlier in many states), with measurable postsecondary goals.

The team includes the parents; at least one regular education teacher if the child is or may be in regular education; at least one special education teacher; a district representative qualified to supervise specially designed instruction, knowledgeable about the general curriculum, and knowledgeable about the availability of district resources; someone who can interpret evaluation results; others with knowledge or expertise at the discretion of the parent or the district; and the child, whenever appropriate — and always when transition is discussed.

Parents are full members of the team, not observers. Winkelman v. Parma City School District, 550 U.S. 516 (2007) held that IDEA grants parents independent, enforceable rights, which they may prosecute pro se in federal court on their own behalf — a holding that rests on the statute's treatment of parents as substantive participants rather than as their child's representatives.

Three practices that violate the statute and are widespread:

• Predetermination. Arriving with a completed IEP and presenting it for signature. The team must actually deliberate, and a parent who is handed a finished document has been denied meaningful participation — a procedural violation that can itself constitute a denial of FAPE.
• "We don't offer that." Services are determined by the child's needs, not by what the district has staffed. Availability is a district problem, not an eligibility criterion.
• Goals without baselines or measurement. A goal that cannot be measured cannot show progress, and it is the most common substantive defect in IEPs.

Part V: Least restrictive environment

20 U.S.C. § 1412(a)(5) requires that, to the maximum extent appropriate, children with disabilities be educated with children who are not disabled, and that removal from the regular educational environment occur only when the nature or severity of the disability is such that education in regular classes with the use of supplementary aids and services cannot be achieved satisfactorily.

The order of the analysis matters. The question is not "where does this child fit among our existing programs?" It is: can this child be educated in the regular classroom with supplementary aids and services? Only if the answer is no does the team move to a more restrictive setting, and then only as far as necessary.

The continuum of alternative placements must be available: regular class with supports, resource room, separate class, separate school, residential, home, and hospital. A district that offers only two options has not met the requirement.

LRE is individualized, not categorical. A placement decision made because of a child's disability label rather than their needs is unlawful.

Part VI: The procedural safeguards — where the statute's force lives

20 U.S.C. § 1415 is the heart of the Act.

Prior written notice. The district must give written notice a reasonable time before it proposes or refuses to initiate or change the identification, evaluation, educational placement, or provision of FAPE. The notice must describe the action, explain why, describe each evaluation procedure and record relied on, describe other options considered and why they were rejected, and state the parent's protections.

This is the single most useful tool a parent has. Any time a district says no, the response is: "Please provide prior written notice." It converts a hallway conversation into a written, dated, reasoned position that can be tested — and it frequently causes the answer to change, because a rationale that cannot be written down is often one that will not survive being written down.

Consent. Required for initial evaluation, reevaluation, and initial provision of services, and revocable in writing.

Access to records under IDEA and FERPA, including the right to inspect before any meeting.

The right to participate in all meetings concerning identification, evaluation, placement, and FAPE.

Stay put. During the pendency of any due process proceeding, the child remains in the then-current educational placement unless the parties agree otherwise. This is an automatic injunction that requires no showing of irreparable harm, and it is enormously powerful: it prevents a district from changing placement while a dispute is litigated.

The right to an independent educational evaluation, discussed above.

Dispute resolution: a state complaint to the education agency (with a 60-day investigation and a written decision); mediation (voluntary, free, and with a binding written agreement); a resolution session required within 15 days of a due process complaint; and a due process hearing before an impartial hearing officer.

Deadlines that matter: a due process complaint must generally be filed within two years of when the parent knew or should have known of the alleged violation (or a different state period); the district must respond within 10 days; and appeal to state or federal court must be filed within 90 days of the hearing decision (or a state period).

Part VII: Discipline

Special rules apply when a child with a disability is removed for behavior.

Ten cumulative school days of removal in a school year is the threshold. Beyond it, a change of placement occurs, triggering obligations.

The manifestation determination review must occur within 10 school days of any decision to change placement for a disciplinary violation. The team asks two questions: was the conduct caused by, or did it have a direct and substantial relationship to, the child's disability? And was it the direct result of the district's failure to implement the IEP?

If the answer to either is yes, the child returns to the placement (with exceptions below), and the team must conduct a functional behavioral assessment and implement or revise a behavior intervention plan.

If the answer to both is no, the child may be disciplined as any other student — but services must continue so that the child continues to progress toward IEP goals.

Special circumstances — weapons, drugs, or serious bodily injury — permit removal to an interim alternative educational setting for up to 45 school days regardless of the manifestation determination.

Protection for children not yet identified. A child not yet found eligible may assert IDEA's protections if the district had knowledge the child had a disability before the behavior occurred — including where a parent expressed concern in writing, requested an evaluation, or a teacher raised specific concerns.

Part VIII: Remedies

Compensatory education — services to make up for a denial of FAPE. Some courts apply an hour-for-hour approach; the better and more common approach is qualitative, asking what services would place the child in the position they would have occupied but for the violation.

Private placement reimbursement. Forest Grove School District v. T.A., 557 U.S. 230 (2009) held that IDEA authorizes reimbursement for private special education services even where the child had never previously received special education from the public district. The requirements: the district failed to provide FAPE, the private placement was appropriate, and the equities favor reimbursement — which in practice means the parent gave the statutory 10 business days' notice of the intent to place privately and seek reimbursement, or gave notice at the last IEP meeting. Missing that notice is the most common reason reimbursement is reduced or denied.

Attorney's fees are available to a prevailing parent, with reductions for unreasonable protraction and a bar on fees for work after a rejected settlement offer that was not bettered.

Exhaustion, and its limits. Two cases define the boundary. Fry v. Napoleon Community Schools, 580 U.S. 154 (2017) held that IDEA's exhaustion requirement applies only where the gist of the complaint is the denial of FAPE — and supplied two diagnostic questions: could the same claim be brought if the conduct occurred at a public facility that is not a school, and could an adult employee have brought essentially the same grievance? If yes to both, the claim is probably not about FAPE and need not be exhausted. And Luna Perez v. Sturgis Public Schools, 598 U.S. 142 (2023) held unanimously that a plaintiff seeking compensatory damages — a remedy IDEA does not provide — need not exhaust IDEA's administrative process before bringing an ADA claim.

Part IX-A: The dispute paths, compared

Parents frequently escalate to the wrong forum, which costs months. The four paths do different things.

Three practical rules.

Use the state complaint far more than parents do. It is free, requires no lawyer, has a hard 60-day deadline, and is very effective for the most common violations — which are procedural. "The IEP says 60 minutes weekly of speech therapy and the service logs show 14 sessions in a 36-week year" is a complaint that wins on paper.

Mediation and due process are not sequential. Filing a due process complaint automatically triggers a resolution session within 15 days, and mediation may be requested at any time. Filing does not foreclose settlement; it usually accelerates it.

Filing triggers stay put. The child remains in the then-current placement while the proceeding is pending. That is sometimes the whole reason to file — and sometimes a reason not to, if the current placement is the problem.

Part IX-B: Building the record before you need it

Special education disputes are decided on documents, and the documents are created months earlier by the parent.

The chronological binder. Every evaluation, every IEP and amendment, every progress report, every prior written notice, every email, every incident and discipline report, every work sample, and every medical or clinical record — in date order, with a one-page index. Bring it to every meeting.

The data request, in writing, before every meeting: "Please provide, at least five school days before the meeting, all evaluation data, progress monitoring data, service logs, behavior data, and work samples the team will consider." You are entitled to review records before a meeting, and a team that has not sent the data has not prepared for a discussion of it.

Service logs are the single most productive request. An IEP promises a quantity of service. The logs show what was delivered. The gap between them is the most common and most provable violation in the field, and districts frequently have not compared the two themselves.

The follow-up email after every meeting. Within 24 hours, and neutral in tone: "Thank you for meeting today. My understanding is that the team agreed to X, that the district declined Y for the reason Z, and that the district will provide A by [date]. Please correct anything I have misstated." An uncorrected summary becomes the record, and the practice frequently produces corrections that are themselves useful.

Independent evaluations. A private evaluation reframes a dispute from a disagreement into a conflict of expert evidence — which is a much better position. Request one at public expense when you disagree with the district's; obtain one privately when speed matters. Either way, the district must consider it.

And keep the child's work. A folder of graded work across a semester is more persuasive to a hearing officer than any narrative about progress, because it is contemporaneous and nobody made it for the litigation.

Part X: Related services, and what districts most often decline

The IEP must include the related services required for the child to benefit from special education, and the statutory list is long and under-used. Districts most frequently decline these, and most frequently should not:

• Speech-language pathology and audiology, including assistive listening.
• Occupational and physical therapy — including sensory and fine motor supports where they affect access.
• School health and school nurse services, including services a nurse or trained person can perform, which the Supreme Court has held a district must provide where required for a child to attend.
• Counseling and psychological services, including social work services and parent counseling and training.
• Behavioral supports — a functional behavioral assessment and a behavior intervention plan, which should be developed before behavior escalates to discipline rather than afterward.
• Assistive technology — devices and services, including evaluation, and including devices for home use where required for FAPE.
• Transportation, including specialized equipment, an aide, or a shortened route where the disability requires it.
• Orientation and mobility for children with visual impairments.
• Interpreting services.
• Extended school year services, where the child would suffer significant regression and slow recoupment without them. ESY is not a summer program for everyone; it is an individualized determination, and it may not lawfully be limited by district policy to particular disability categories or offered only in one format.
• Transition services, beginning by 16 in federal law and earlier in many states, with measurable postsecondary goals and coordinated activities — the most neglected part of most IEPs.

Two sentences worth knowing. "That's not something we provide" is not a lawful answer; needs drive services. And "we can't afford it" is not a lawful answer either — cost may inform a choice between two appropriate options, but it cannot justify denying an appropriate program.

Part XI: Turning 18, and after school

Two transitions catch families unprepared.

The transfer of rights at the age of majority. In most states, IDEA rights transfer from the parent to the student at 18. The district must notify both a year in advance. Families should decide before that date among the available options: supported decision-making (an agreement recognizing that the young adult decides with help), a power of attorney or health care proxy signed voluntarily by the student, a delegation of educational rights where the state permits it, or — as a last resort — guardianship, which is the most restrictive option and should not be the default. Many districts hand out guardianship information as though it were the only route; it is not.

The change of legal regime after school. IDEA ends at graduation with a regular diploma or at the state's maximum age, and there is no IEP afterward. Postsecondary institutions and employers are governed by Section 504 and the ADA, which require reasonable accommodations — not specially designed instruction, not modified curricula, and not the entitlement structure IDEA provides. The obligation to identify the disability also shifts: the student must self-identify and provide documentation.

What to do in the last two years of school, which is what transition services are for: apply to the state vocational rehabilitation agency, which can fund training, assistive technology, and job supports; apply for adult services waivers, which frequently have multi-year waiting lists that should be joined early; obtain current evaluations, because a college disability services office will require documentation and an IEP is not sufficient; and understand the diploma decision — accepting a regular diploma ends IDEA eligibility, which is a real trade-off where the student would benefit from remaining until the maximum age.

Part XI-A: Three disputes, three forums

The service that was never delivered. An IEP provides 60 minutes weekly of speech therapy. The parent requests service logs and finds 14 sessions delivered across a 36-week year — the therapist position was vacant for a semester and nobody told the family.

The right forum is a state complaint. It is free, requires no lawyer, and produces a written decision within 60 days. The evidence is two documents: the IEP and the logs. The remedy typically ordered is compensatory education — the missing hours, provided going forward — plus corrective action for the district. A due process hearing would reach the same result in nine months and cost tens of thousands.

The refusal to evaluate. A second grader is two years behind in reading. The school says he is "making progress in the intervention block" and declines to evaluate, for the third time.

The right move is not a complaint yet. It is a written request for evaluation, followed by: "Please provide prior written notice of the district's refusal, including the data relied upon and the other options considered and rejected." That notice frequently produces the evaluation, because the rationale — that a child two years behind after two years of intervention does not warrant assessment — is hard to write down. If the notice comes back refusing, the parent now has a dated written position to attach to a state complaint or a due process filing, and the child find analysis is straightforward.

The placement dispute. A district proposes moving a child with autism from a general education classroom with supports to a self-contained program in another building. The parent disagrees.

This is a due process case, and filing has an immediate consequence: stay put keeps the child in the current placement while the matter is pending. The substantive question is least restrictive environment — whether education in the regular class with supplementary aids and services can be achieved satisfactorily — and the burden of the analysis falls on whether the district actually tried the supports. The parent's strongest evidence is usually an independent educational evaluation recommending specific supports the district has not attempted, plus a record showing what was and was not implemented.

The pattern. Procedural violations go to the state complaint, which is fast and free. Refusals go to prior written notice first, which is free and frequently dispositive. Substantive disagreements about the program go to due process, which is slow and expensive and where stay put is often the immediate objective.

Part XI-B: Section 504 on its own

Most writing about special education treats Section 504 as the consolation prize for children who do not qualify under IDEA. That understates it considerably.

The eligibility standard is much broader, and it got broader still with the ADA Amendments Act, which directs that "substantially limits" be construed broadly, that mitigating measures (medication, hearing aids, learned behavioral adaptations) be disregarded in assessing whether an impairment substantially limits a major life activity, and that an impairment that is episodic or in remission qualifies if it would substantially limit when active. Major life activities expressly include learning, reading, concentrating, thinking, communicating, and the operation of major bodily functions.

The practical consequence: children with ADHD, anxiety, depression, diabetes, epilepsy, severe allergies, asthma, Crohn's disease, and long-term effects of concussion frequently qualify under 504 even where they do not need specially designed instruction — and a district that says "he doesn't qualify because his grades are fine" has applied the wrong standard. Good grades achieved through extraordinary effort, or through accommodations already being provided informally, do not defeat eligibility.

What a 504 plan can require: extended time; a reduced-distraction setting; preferential seating; a note-taker or copies of notes; permission to leave class for medical care; a health care plan and trained staff for a medical condition; access to food, water, or a bathroom; modified attendance policies for a chronic condition; assistive technology; behavioral supports; and modified physical education. It can also require program access changes — an accessible route, an accessible field trip, an interpreter at an evening event.

Where 504 reaches further than IDEA. It applies to every program and activity of the school, including athletics, clubs, field trips, before- and after-care, and school-sponsored events. A child excluded from a team, a trip, or an after-school program because of a disability has a 504 claim regardless of their IEP.

And it reaches the district's own conduct. A 504 or ADA claim for discrimination or retaliation — as opposed to a claim for denial of FAPE — is a different animal from an IDEA claim, is enforced by the Office for Civil Rights or in court, and can carry damages. After Fry and Perez, such a claim frequently need not be exhausted through IDEA's process at all.

The enforcement route parents underuse: a complaint to the Office for Civil Rights of the Department of Education. It is free, requires no lawyer, must generally be filed within 180 days of the discriminatory act, and OCR investigates and can require corrective action. For access, exclusion, and retaliation issues it is frequently faster and better than anything else available.

Part XII: Frequently asked questions

How do I request an evaluation? In writing, dated, delivered to the principal and the special education director. Keep a copy. The timeline runs from consent.

Can the school say they don't have that service? No. Services follow the child's needs. Availability is the district's problem.

What if I disagree with the evaluation? Request an independent educational evaluation at public expense. The district must fund it or promptly file for a hearing to defend its own.

Can I record the IEP meeting? State and district policies vary. Ask in advance and in writing; where recording is permitted for the district it generally must be permitted for the parent.

My child is failing but the school says they're making progress. Ask for the data, in writing, and request prior written notice of any refusal. Progress must be measurable and reported.

Does an IEP follow my child to a new district? The new district must provide comparable services until it adopts the old IEP or develops a new one.

Can they suspend my child? Up to 10 cumulative days as any other student. Beyond that, a manifestation determination is required and services must continue.

Do I need a lawyer? Not for most IEP work. Parent training and information centers exist in every state and are free. Get counsel for a due process hearing, a private placement claim, or a district that will not engage.

Part XIII: For parents — what actually works

1. Put every request in writing, with a date, and keep a copy. Email is ideal. This single habit changes outcomes more than anything else.
2. Ask for prior written notice whenever the answer is no. "Please provide prior written notice of that refusal" is the most useful sentence in special education.
3. Request records before every meeting, including evaluations, work samples, data collection, and progress reports.
4. Bring someone. A friend, an advocate, or a relative — as a second set of ears and a witness. You have the right to bring people with knowledge or expertise.
5. Ask for the data. Not "is he doing better" but "what is the baseline, what is the current level, and how was it measured?"
6. Do not sign at the meeting if you are unsure. You may take the document home. Consent to services and agreement with an IEP are different things, and you may consent to some parts and not others in most states.
7. Write a follow-up email after every meeting summarizing what was said and agreed. It becomes the record.
8. Keep a chronological binder: evaluations, IEPs, progress reports, work samples, emails, incident reports, and medical records.
9. Give the 10-business-day notice before any private placement for which you will seek reimbursement.
10. Use the free help. Every state has a federally funded parent training and information center, and a protection and advocacy organization. Both are free and both do this daily.
