TL;DR
The Individuals with Disabilities Education Act (IDEA), 20 U.S.C. § 1400 et seq., is the federal law that requires public schools to give every eligible child a free appropriate public education through an Individualized Education Program. Schools must evaluate within 60 days of written consent, review the IEP once a year, and provide services at no cost to families. Parents have enforceable rights at every step.
What federal law actually governs IEPs?
The Individuals with Disabilities Education Act, almost always shortened to IDEA, is the core federal statute. Its full citation is 20 U.S.C. §§ 1400-1482, and it was most recently reauthorized in 2004 as the Individuals with Disabilities Education Improvement Act. The U.S. Department of Education enforces it through its Office of Special Education Programs (OSEP). [1]
IDEA does two things at once. It funds special education at the state and local level, and it attaches legal strings to that funding. Schools that take federal special education money must follow every procedural and substantive rule in the statute. That is the lever parents pull. A school that violates IDEA risks losing federal dollars.
A second law, Section 504 of the Rehabilitation Act of 1973 (29 U.S.C. § 794), also protects students with disabilities, but through a different mechanism. Section 504 is a civil rights law that bars discrimination. It requires accommodations but does not require an IEP or specialized instruction. The two laws overlap. They are not the same. If you want the differences side by side, the IEP vs 504 comparison is worth reading before your next school meeting. [2]
IDEA covers children from birth through age 21, or through high school graduation, whichever comes first. Part C covers infants and toddlers from birth to age 3 through early intervention. Part B covers children ages 3 through 21 in public schools, and that is the part this guide focuses on. [1]
What does IDEA's 'free appropriate public education' actually mean?
IDEA requires every eligible child to receive a "free appropriate public education," commonly called FAPE. The word "free" is absolute. Families cannot be billed for evaluations, IEP services, specialized instruction, or assistive technology the IEP requires. [1]
"Appropriate" has been argued in courts for decades. The Supreme Court clarified the standard in Endrew F. v. Douglas County School District (2017), ruling that an IEP must be "reasonably calculated to enable a child to make progress appropriate in light of the child's circumstances." That quote comes from the unanimous opinion written by Chief Justice Roberts, and it raised the bar above a mere de minimis benefit. Schools cannot coast on minimal progress anymore. [3]
"Public education" means the public school system is the provider of record, even when services happen in a private setting. If the district cannot provide an appropriate program, it has to pay for a private placement.
FAPE also covers related services: speech-language therapy, occupational therapy, physical therapy, counseling, transportation, and assistive technology, among others, when the child needs them to benefit from special education. The list at 20 U.S.C. § 1401(26) is illustrative, not exhaustive. That matters. If your child needs a service that is not spelled out, the statute still reaches it. [1]
What are the 13 disability categories that qualify a child for an IEP?
IDEA lists exactly 13 disability categories. A child has to meet the criteria under at least one of them, the disability has to adversely affect educational performance, and the child has to need specially designed instruction. All three conditions matter. Miss any one and the child does not qualify. [1]
| # | Disability Category | Common abbreviation |
|---|---|---|
| 1 | Specific Learning Disability | SLD |
| 2 | Other Health Impairment | OHI |
| 3 | Autism Spectrum Disorder | ASD |
| 4 | Emotional Disturbance | ED |
| 5 | Speech or Language Impairment | SLI |
| 6 | Visual Impairment (including blindness) | VI |
| 7 | Deafness | (none) |
| 8 | Hearing Impairment | HI |
| 9 | Deaf-Blindness | (none) |
| 10 | Orthopedic Impairment | OI |
| 11 | Intellectual Disability | ID |
| 12 | Traumatic Brain Injury | TBI |
| 13 | Multiple Disabilities | (none) |
For struggling readers and children with dyslexia, the relevant category is almost always Specific Learning Disability (SLD). IDEA defines SLD as "a disorder in one or more of the basic psychological processes involved in understanding or using language, spoken or written," and that definition explicitly names dyslexia along with dyscalculia and dysgraphia. [1]
Other Health Impairment (OHI) is the category schools usually use for children with ADHD, because ADHD has no category of its own. Autism is the fastest-growing eligibility category by prevalence. Between 2012 and 2022, the share of IDEA students served under Autism rose from roughly 8% to about 12% of all children with IEPs, according to OSEP's annual data. [4]
Here is what surprises many parents: a child does not need a medical diagnosis to qualify. Eligibility is decided by the school's multidisciplinary team based on evaluation data, not by a doctor's letter. A dyslexia diagnosis from a private clinician is useful evidence. It is not legally required.
What are the exact timelines schools must follow under IDEA?
IDEA is unusually specific about deadlines, and schools often count on parents not knowing them. These are the ones that matter most. [1][4]
Initial evaluation: Once the school receives written parental consent for an initial evaluation, it has 60 calendar days to finish the evaluation and hold an eligibility meeting. Some states set shorter timelines, a few as low as 30 or 45 days. Check your state's special education regulations for the local rule.
IEP development: Once a child is found eligible, the first IEP has to be in place and services have to start "as soon as possible" after the eligibility meeting. OSEP guidance reads that as days to a few weeks, not months.
Annual review: Every IEP gets reviewed at least once a year. The meeting has to happen before the anniversary date of the last IEP, not after it.
Reevaluation: The school has to reevaluate the child at least once every three years, the "triennial" re-eval, unless both parent and school agree it is unnecessary. Parents can request a reevaluation any time, and the school has to either conduct one or explain in writing why it is refusing.
Prior Written Notice (PWN): Any time the school proposes to change, or refuses to change, identification, evaluation, placement, or services, it has to give parents written notice beforehand. This is one of the most underused protections in the statute. If the school verbally agrees to something but never sends a PWN, get it in writing.
A note on delays. Miss the 60-day window and the school is in procedural violation of IDEA. Document the date you submitted written consent. Follow up in writing the day the deadline passes.
What must be inside a legally compliant IEP document?
IDEA at 20 U.S.C. § 1414(d) spells out exactly what belongs in every IEP. An IEP missing a required component is not legally compliant, even if the school handed you a thick folder. [1]
Required components:
1. Present levels of academic achievement and functional performance (PLAAFP). This is the baseline: where the child is right now, based on data. 2. Measurable annual goals. Each goal has to be measurable, meaning someone could collect data and tell you whether it was met. 3. A description of how progress toward goals gets measured and when progress reports go to parents. 4. A statement of the special education and related services provided, including frequency, duration, and location. 5. An explanation of the extent, if any, to which the child will NOT participate with non-disabled peers in general education (the least restrictive environment, or LRE, justification). 6. Any accommodations for state and district assessments. 7. The projected start date for services and their anticipated frequency, location, and duration. 8. Beginning at age 16, or younger in some states, transition services: measurable postsecondary goals and the services needed to reach them.
Vague goals like "Johnny will improve his reading" are not legally compliant, because you cannot measure them. A compliant goal reads more like this: "By June 2026, given a grade-2 passage, the student will read 70 correct words per minute with 95% accuracy on 4 of 5 trials."
If you want the full IEP meaning and structure before your meeting, read the document yourself rather than waiting for the school to walk you through it. Parents who show up having already read the draft get better outcomes. That is more than an opinion. Research on IEP participation consistently links informed parents to more ambitious goals and more services. [5]
What parental rights does IDEA guarantee?
This is where IDEA is genuinely strong. The law hands parents procedural safeguards that are real and enforceable. Schools have to give you a written copy of these rights, the Procedural Safeguards Notice, at least once a year and at other key moments. [1][2]
The rights that matter most in practice:
Consent: The school has to get your written consent before an initial evaluation and before it starts initial special education services. You can revoke consent for services at any time, in writing.
Participation: You are a required member of the IEP team, not a guest. The school cannot hold an IEP meeting without you unless it makes multiple documented attempts to reach you and you never respond.
Access to records: Under IDEA and the Family Educational Rights and Privacy Act (FERPA), you have the right to inspect and review every education record about your child. The school has to comply within 45 days. [6]
Independent Educational Evaluation (IEE): If you disagree with the school's evaluation, you can request an IEE at public expense. The school has to either pay for it or file for a due process hearing to defend its own work. Few parents know this one exists.
Dispute resolution: IDEA gives you three formal channels: a State Complaint (filed with the state education agency, free, resolved within 60 days), Mediation (voluntary, confidential, faster than a hearing), and a Due Process Hearing (the most formal, quasi-judicial, with a neutral hearing officer). [2]
Stay-put: While a due process dispute is pending, the child stays in the current placement. The school cannot move the child or cut services while you are fighting the case.
No retaliation: Schools cannot retaliate against parents who use their IDEA rights. If you feel pressured to stop asking questions, document every interaction in writing from that point on.
What is the least restrictive environment (LRE) rule?
IDEA requires that children with disabilities be educated with non-disabled peers to the maximum extent appropriate. This is the Least Restrictive Environment requirement, codified at 20 U.S.C. § 1412(a)(5). [1]
LRE does not mean every child sits in a general education classroom all day. It means the IEP team has to justify any removal from general education with data and reasoning. The burden sits on the school to show why a more restrictive setting is necessary. It does not sit on the parent to prove the child belongs in the mainstream classroom.
The LRE continuum, from least to most restrictive, looks roughly like this:
- General education classroom with supports and accommodations
- General education with pull-out services for part of the day
- Resource room for a significant portion of the day
- Self-contained special education classroom within a general school
- Special day school (separate campus)
- Residential placement
- Home or hospital instruction
Most children with reading disabilities like dyslexia are educated in general education settings for most of the day, with pull-out time for specialized reading instruction. The research backs explicit, systematic phonics-based intervention delivered in small groups, so 30 to 45 minutes of intensive pull-out reading is usually both appropriate and LRE-compliant. [7]
If a school proposes a more restrictive placement, ask two questions in writing. What data shows the child cannot make adequate progress in a less restrictive setting with appropriate supports? What specific supplementary aids and services were tried before this recommendation?
How does IDEA handle reading disabilities and dyslexia specifically?
Congress wrote dyslexia straight into IDEA. The statute now states that Specific Learning Disability includes conditions such as "perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia." The word is in the text, more than in guidance. [1]
Beyond eligibility, IDEA requires that reading instruction for students with SLD rest on peer-reviewed research to the extent practicable (20 U.S.C. § 1414(d)(1)(A)(i)(IV)). That phrase "peer-reviewed research" has teeth. Schools cannot use reading programs that lack an evidence base. Structured literacy grounded in systematic phonics has the strongest research support for students with dyslexia. [7][8]
IDEA also folds in Response to Intervention (RTI), now often called Multi-Tiered System of Supports (MTSS). Schools can use RTI data as part of the SLD eligibility decision. What they cannot do is use RTI to delay or deny an initial evaluation. The U.S. Department of Education has stated plainly that using RTI to postpone an evaluation violates the law. [9]
Has your child been stuck in Tier 2 interventions for more than a year with no measurable progress? That is your signal to submit a written evaluation request. RTI is a general education support system. It is not a substitute for a special education evaluation when a child is not responding.

If you are at the very start, read what an IEP is and how to get one first.
What happens if a school violates IDEA? What can parents do?
Parents have real remedies when schools break the rules. The options differ in cost, speed, and likely outcome. [1][2]
State Complaint: File a written complaint with your State Education Agency (SEA). The SEA has to investigate and issue a written decision within 60 days. It is free, needs no lawyer, and can produce corrective actions and compensatory services. This is the fastest, cheapest path for procedural violations like a missed timeline or a missing PWN.
Mediation: Both sides have to agree. A neutral mediator helps negotiate a resolution, and any agreement is legally binding. Mediation is confidential, which means schools tend to talk more freely, and it usually moves faster than a hearing. IDEA makes it free to the family.
Due Process Hearing: A formal quasi-judicial proceeding before a neutral hearing officer. It is adversarial and expensive, since parents often hire special education attorneys, and it can run for months. But if a school has denied FAPE for a long stretch, a parent who wins can be awarded compensatory education to make up the lost time. When the parent prevails, IDEA lets courts award reasonable attorney fees. [1]
Federal Complaint to OCR: The Department of Education's Office for Civil Rights handles complaints under Section 504 and the Americans with Disabilities Act. OCR does not take IDEA complaints directly, but if your child is being discriminated against, OCR is the right door. [2]
One practical note. Document everything. Confirm verbal conversations by email, keep copies of every document the school sends, and date-stamp your own letters. The record in a dispute gets built from paper, not memory.
How do state IEP laws differ from the federal baseline?
IDEA sets the floor. States can add protections. They cannot take any away. Several states have gone well past the federal baseline. [1][10]
Examples of state-level additions:
- California starts the evaluation clock at 60 days from a written referral, not from consent, which starts it earlier.
- Texas requires the IEP team to consider dyslexia specifically and to address it in the IEP once it is identified.
- New York uses a 60-day timeline but also mandates transition planning starting at age 15, one year earlier than the federal floor.
- Several states, Florida and North Carolina among them, have passed separate dyslexia laws requiring screeners in kindergarten and the early grades, which feeds straight into the IEP pipeline.
Here is the practical takeaway. Look up your state's special education regulations, more than the federal IDEA text. Your state education agency's website has the exact timelines, expanded eligibility criteria, and procedural differences that apply in your district. This can matter enormously, because a school in full compliance with the federal floor can still be breaking a stricter state rule.
If you are in Maryland and your child has an IEP, the state runs a specific online system for IEP management. The md iep online guide explains how to access and read those records.
What rights do parents have in IEP meetings?
Parents are full, equal members of the IEP team under IDEA. That is not a polite fiction. It is a statutory requirement at 20 U.S.C. § 1414(d)(1)(B). [1]
You have the right to:
- Bring anyone you want. A private advocate, an attorney, a therapist, a knowledgeable friend. You do not need permission, though advance notice is courteous.
- Receive a copy of the IEP draft before the meeting. Federal law does not force schools to send a draft in advance, but many will if you ask. Ask in writing.
- Ask that the meeting be rescheduled to a time that works for you. The school has to make a reasonable effort to schedule at a mutually convenient time.
- Record the meeting. Federal law does not prohibit it, but state law varies. Some states require all-party consent. Check your state's recording law before you bring a device.
- Disagree with the IEP and refuse to sign consent for services. Signing does not mean you agree with every word. It means you consent to services starting. Write your objections on the signature page or in a follow-up letter.
- Request another meeting any time you think the IEP needs revision. The school has to respond to a written request for an IEP meeting.
One move most parents miss. Send written input to the team before the meeting and ask that it go into the meeting notes. That builds a paper trail and puts your concerns formally on record. [5]
How does an IEP differ from a 504 plan, and which one does your child need?
This is one of the most common questions parents ask. Short answer: an IEP provides specialized instruction and services, while a 504 plan provides accommodations. Two separate laws, two different standards. [2]
An IEP requires the child to meet IDEA's eligibility criteria: one of the 13 categories, plus adverse educational impact, plus a need for specialized instruction. It delivers a detailed, legally binding program with goals, services, timelines, and every procedural protection described in this guide.
A 504 plan requires the child to have a physical or mental impairment that substantially limits a major life activity, and learning counts as one. The threshold is lower than IDEA's. A child who does not qualify for an IEP may still qualify for a 504. But a 504 provides accommodations (extended time, preferential seating, text-to-speech), not specialized instruction. If a child needs a fundamentally different way of being taught to read, a 504 falls short.
For struggling readers, the decision usually runs like this. If the child needs a different program of reading instruction delivered by a specialist, push for an IEP evaluation. If the child is keeping up academically but needs supports to access instruction, a 504 may be enough. If you are unsure, request the full evaluation anyway. Eligibility can always be discussed after the data comes in.
The full IEP vs 504 breakdown lays out every difference side by side.
What should parents do right now if they think their child needs an IEP?
The single most important move is to submit a written request for a special education evaluation. Not a phone call. Not a comment at a conference. A dated letter or email, addressed to the principal and the special education director, stating that you are formally requesting an evaluation for special education eligibility under IDEA. [1][9]
Why writing matters: the 60-day clock starts when the school receives written consent. Make only verbal requests and the clock never starts. Schools sometimes tell parents to "wait and see" or let the current intervention run its course. That advice can push services back by months or years. You can always request the evaluation while the intervention continues.
After you submit the request:
1. The school has to respond with either a written consent form for evaluation or a written refusal with reasons (Prior Written Notice). If they refuse, they have to explain why in writing, and you can file a state complaint. 2. Once you sign the consent form, write down the date. Count 60 calendar days (or your state's shorter window) forward. That is the legal deadline for the evaluation to be complete. 3. Show up to the eligibility meeting with data: report cards, samples of the child's work, any private evaluations, and written observations from tutors or coaches. 4. If the child is found eligible, the IEP meeting has to follow quickly. Push for a service start date measured in days, not weeks.
The ReadFlare parent advocacy kit includes a sample evaluation request letter, a timeline tracker, and a checklist of questions for the eligibility meeting. It is free to download.

Frequently asked questions
What does IDEA stand for and what law number is it?
IDEA stands for the Individuals with Disabilities Education Act. Its federal citation is 20 U.S.C. §§ 1400-1482. It was originally passed in 1975 as the Education for All Handicapped Children Act and most recently reauthorized in 2004. It is the law requiring public schools to provide IEPs to eligible children with disabilities.
Can a school refuse to evaluate my child for an IEP?
Yes, a school can refuse, but it has to give you written notice (Prior Written Notice) explaining its reasons. You can challenge that refusal by filing a state complaint with your State Education Agency or requesting mediation. State agencies have repeatedly ordered schools to evaluate children when the refusal lacked adequate data. Never accept a verbal refusal without following up in writing.
How long does a school have to complete an IEP evaluation?
Under federal IDEA, schools have 60 calendar days from the date of written parental consent to complete the evaluation and hold an eligibility meeting. Some states set shorter windows, as few as 30 days. The clock starts when the school receives your signed consent form, not when you verbally agreed or first asked.
Does my child need a dyslexia diagnosis to get an IEP?
No. IDEA eligibility is decided by the school's multidisciplinary evaluation team, not by a doctor's or clinician's diagnosis. A private dyslexia evaluation is useful evidence but not required. The team looks at whether the child has an SLD, whether it adversely affects educational performance, and whether specially designed instruction is needed. All three conditions have to be present.
What is an Independent Educational Evaluation and who pays for it?
An IEE is an evaluation done by a qualified examiner who does not work for the school district. If you disagree with the school's evaluation, you can request an IEE at public expense under IDEA. The school has to either pay for it or file for a due process hearing to defend its own evaluation. Parents can also pay for a private IEE at any time.
Can a school hold an IEP meeting without me?
No, not without documentation. IDEA requires the school to ensure parent participation, including notifying you well in advance and at a mutually convenient time. It can only proceed without you if it documents multiple failed attempts to reach or include you. Even then, it has to keep that documentation, and you keep every right to review and object afterward.
What is 'stay-put' and how does it protect my child?
Stay-put, at 20 U.S.C. § 1415(j), means that during any IDEA dispute or due process proceeding, the child stays in their current educational placement. The school cannot change services, move the child to a different setting, or reduce supports while the dispute is unresolved. This stops schools from making retaliatory placement changes after parents file complaints.
Are IEP services free to families?
Yes. IDEA requires all special education and related services under an IEP to be at no cost to parents. That covers evaluations, specialized instruction, speech therapy, occupational therapy, transportation, and assistive technology when they are part of the IEP. Schools cannot bill families or require insurance to cover services the IEP mandates.
What is Prior Written Notice and when must the school send it?
Prior Written Notice (PWN) is a written document the school has to give parents any time it proposes or refuses to change the child's identification, evaluation, educational placement, or provision of FAPE. It has to describe what the school proposes or refuses to do and why. If the school makes verbal promises or refusals without a PWN, ask for it in writing right away.
How often must an IEP be reviewed?
At least once a year. The annual review meeting has to happen before the anniversary date of the current IEP. The full reevaluation of eligibility has to happen at least every three years. Parents can request a review meeting or a reevaluation any time in writing, and the school has to either comply or provide written notice explaining why it declines.
What transition planning does IDEA require for older students?
Beginning at age 16, IDEA requires the IEP to include measurable postsecondary goals for education, employment, and where appropriate, independent living skills. It also has to include transition services designed to help the student reach those goals. Some states start transition planning at age 14 or 15. The student has to be invited to their own IEP meeting when transition is on the agenda.
What is the difference between an IEP goal and an accommodation?
A goal is a measurable target for skill growth that instruction is designed to achieve, such as reaching a specific reading fluency rate. An accommodation is a change in how the student accesses instruction or shows knowledge, like extended time or text-to-speech, that does not change the content taught. IEPs include both, but specialized instruction to meet goals is what separates an IEP from a 504 plan.
Can parents be reimbursed for a private school placement if the public school fails to provide FAPE?
Yes, under certain conditions. The Supreme Court ruled in Florence County School District v. Carter (1993) that parents who unilaterally place a child in a private school because the public school failed to provide FAPE may be reimbursed, even if the private school is not state-approved, as long as the placement is appropriate. The process runs through due process or court, and the outcome depends heavily on documentation of the school's failure.
What is compensatory education and can my child get it for past violations?
Compensatory education is extra services awarded to make up for a period when the school failed to provide FAPE. If a due process hearing officer or court finds the school violated IDEA, they can order the district to provide services beyond the current IEP to compensate for lost educational time. The amount usually ties to how long the violation lasted and what services were denied.
