IDEA in Schools: Eligibility, IEP Process, and Parent Rights

The Individuals with Disabilities Education Act, known as IDEA, is the federal law that requires public schools to find children with disabilities, evaluate them, and provide a free appropriate public education tailored to each child’s needs at no cost to the family. IDEA in schools covers eligible students from age 3 through 21 through what’s called Part B, and more than 8 million children and infants receive services under the law nationwide.¹ If your child is struggling and you think a disability may be involved, IDEA gives you a specific process to request an evaluation, a seat at the table when decisions are made, and legal tools if the school falls short.

Who Qualifies for Services

Eligibility under IDEA has two parts. A child must have a disability that fits one of 13 federal categories, and that disability must require special education and related services. A diagnosis alone is not enough; the disability has to affect educational performance to the point that specialized instruction is necessary.²

The 13 categories are:

Autism — a developmental disability affecting communication and social interaction, generally evident before age three.
Deaf-blindness — simultaneous hearing and visual impairments causing severe developmental and communication needs.
Deafness — a hearing impairment severe enough to impair processing of spoken language, with or without amplification.
Emotional disturbance — a condition marked by characteristics such as an inability to learn or maintain relationships, exhibited over a long period to a marked degree.
Hearing impairment — a hearing loss, permanent or fluctuating, that is not severe enough to qualify as deafness.
Intellectual disability — significantly below-average intellectual functioning combined with deficits in adaptive behavior.
Multiple disabilities — two or more simultaneous impairments creating educational needs that cannot be addressed by programs designed for a single disability.
Orthopedic impairment — a severe physical impairment caused by congenital conditions, disease, or injury.
Other health impairment — limited strength, vitality, or alertness due to chronic or acute conditions such as ADHD, asthma, diabetes, or epilepsy.
Specific learning disability — a disorder in psychological processes involved in understanding or using language, affecting abilities like reading, writing, or math.
Speech or language impairment — communication disorders including stuttering, impaired articulation, or voice impairment.
Traumatic brain injury — an acquired brain injury caused by external physical force.
Visual impairment including blindness — an impairment in vision that adversely affects educational performance even with correction.

For children aged 3 through 9, states may also recognize developmental delay as a qualifying category if the child has delays in physical, cognitive, communication, social-emotional, or adaptive development.²

The most common qualifying conditions in schools are specific learning disabilities, speech or language impairments, and other health impairments. In the 2022–23 school year, roughly 2.4 million students were served under the specific learning disability category alone, followed by about 1.26 million with speech or language impairments and 1.16 million with other health impairments.³

How to Get Services: From Referral to IEP

Under a requirement called Child Find, every public school district has an affirmative duty to identify, locate, and evaluate all children with disabilities within its jurisdiction, from birth through age 21. The duty applies regardless of the severity of a child’s disability and extends to children who are homeless, in foster care, attending private schools, or passing their classes. The school cannot wait for a parent to ask; if it suspects a child has a disability, it has to act.⁴

You can also start the process yourself by requesting an evaluation in writing. Once a child is referred, whether by you, a teacher, or through Child Find, the school must obtain your written consent before evaluating. The evaluation has to cover all areas related to the suspected disability and is generally completed within 60 days of consent. If you disagree with the school’s evaluation, you have the right to request an independent educational evaluation at public expense.⁵

A team of qualified professionals and the parents reviews the evaluation results and decides whether the child meets IDEA’s definition of a child with a disability. If the child is found eligible, the IEP team must meet within 30 calendar days to write the Individualized Education Program.⁶ Written parental consent is required before services can begin. The IEP is reviewed and revised at least once a year, and a full reevaluation must occur at least every three years to confirm the child still qualifies.⁵

What the IEP Must Include

The IEP is the written plan that spells out what special education looks like for your child. It is developed by a team that includes you as the parent, at least one general education teacher, a special education teacher, a school district representative, and someone who can interpret evaluation results. The student is invited when transition services are being discussed.⁶

Every IEP must describe how the disability affects the child’s participation in the general curriculum, set measurable annual goals, list the specific special education and related services the school will provide, and include start dates, frequency, and duration for those services. For older students, the IEP must also include transition planning.⁶

The word “appropriate” in “free appropriate public education” carries real weight. In Endrew F. v. Douglas County School District (2017), the U.S. Supreme Court unanimously held that a school’s program must be “reasonably calculated to enable a child to make progress appropriate in light of the child’s circumstances.” The Court rejected the older, lower standard that had allowed schools to offer programs providing only trivially more than no benefit.⁷ If the goals in your child’s IEP would not lead to meaningful progress given who your child is, that is a legal problem, not just a disagreement about strategy.

Related Services the School Must Provide

IDEA requires schools to provide more than classroom instruction. Related services are the supports a child needs to benefit from special education, and the IEP team decides which specific services a child requires.⁸

Common related services include speech-language pathology and audiology, physical therapy, occupational therapy, psychological services, counseling, school health and nursing services, social work services, orientation and mobility services for students who are blind or visually impaired, interpreting services, parent counseling and training, and transportation. Specialized transportation equipment such as adapted buses, lifts, and ramps must be provided when a child’s disability requires it.⁸

One limit worth knowing: schools are not responsible for surgically implanted medical devices such as cochlear implants, including their maintenance or replacement. Schools still must monitor such devices to keep a child safe during the school day.⁹

Parent Rights and Procedural Safeguards

IDEA treats parents as full and equal members of the team making decisions about a child’s education. Schools must give parents a written explanation of all procedural safeguards, obtain parental consent before evaluating a child or starting services, provide prior written notice before changing a child’s identification, evaluation, or placement, and allow parents to inspect the child’s educational records.¹⁰

Prior written notice matters in practice. If the school proposes or refuses to change anything about your child’s evaluation, eligibility, program, or placement, it has to tell you in writing before it happens, with reasons. That paper trail is what lets you push back or file a complaint if you disagree.

Where Your Child Will Be Placed

IDEA requires that children with disabilities be educated alongside non-disabled peers to the maximum extent appropriate. This is the least restrictive environment rule, or LRE. Removing a student from a general education classroom is only supposed to happen when the nature or severity of the disability makes education in that setting unsatisfactory even with supplementary aids and services. In the 2022–23 school year, more than 66% of children with disabilities under IDEA spent 80% or more of the school day in general education classrooms.¹

In practical terms, if the school proposes a separate classroom or a specialized program, it needs to be able to explain why supports in the general classroom would not work. LRE is a legal standard, not a preference.

Discipline: What Protections Your Child Has

IDEA includes specific protections that limit how schools may discipline students with disabilities, so that a child is not punished for behavior that stems from the disability itself.

Schools may suspend or remove a student with a disability for up to 10 school days under the same rules that apply to any student. Once a removal passes 10 days, it counts as a change of placement and the school must convene a manifestation determination review within 10 school days. The review team, which includes the parents and relevant IEP team members, decides whether the behavior was caused by or had a direct and substantial relationship to the child’s disability, or whether it resulted from the school’s failure to implement the IEP.¹¹

If the behavior is found to be a manifestation of the disability, the student generally must return to the prior placement, and the team must conduct or review a functional behavioral assessment and develop or update a behavioral intervention plan. If it is not a manifestation, the school may apply the same discipline it would use for any student, but it must continue providing special education services.¹¹

Regardless of whether behavior is linked to a disability, schools may place a student in an interim alternative educational setting for up to 45 school days if the student brings a weapon to school, possesses or sells illegal drugs, or inflicts serious bodily injury on another person.¹²

When You Disagree With the School

Disputes over evaluations, eligibility, the IEP, or placement are common, and IDEA gives you several ways to resolve them.

Mediation is voluntary and uses a neutral third party to help both sides reach agreement. You can also file a formal complaint with your state education agency. The most adversarial route is a due process hearing, where an impartial hearing officer acts as a judge and issues a binding decision. When you file a due process complaint, the school must hold a resolution session within 15 days to try to settle before a hearing.¹³

A hearing officer must issue a decision within 45 days after the resolution period ends. Under the Supreme Court’s ruling in Schaffer v. Weast (2005), the party requesting the hearing generally bears the burden of proof. Either side may file a civil action in state or federal court within 90 days of the decision.¹³

When a school has failed to provide FAPE, courts and hearing officers may award compensatory education as an equitable remedy. That can take the form of additional services, tutoring, or reimbursement for private school tuition. Courts have held that compensatory awards should put the child in the position they would have been in had the school met its obligations, and there is no rigid hour-for-hour formula; the remedy is tailored to the child’s circumstances and the nature of the school’s failure.¹⁴

Transition Planning for Older Students

For students approaching adulthood, IDEA requires that the IEP include transition planning starting no later than age 16, though many states start earlier. Transition services are a coordinated set of activities focused on moving the student from school to post-school life, including postsecondary education, employment, and independent living.¹⁵

Planning must be based on the student’s strengths, preferences, and interests, and include measurable goals. The team, which includes the student, develops a plan covering instruction, community experiences, employment objectives, and, where appropriate, daily living skills. Before the student graduates or ages out, the school must provide a Summary of Performance documenting academic and functional abilities along with recommendations for meeting postsecondary goals.¹⁶

At least one year before the student reaches the age of majority in your state, the school must give notice that educational decision-making rights will transfer to the student.¹⁶

Children Under Age 3

IDEA in schools begins at age 3. Infants and toddlers from birth through age 2 are served under a separate section of the law, Part C, which uses an Individualized Family Service Plan rather than an IEP and is coordinated by a designated state lead agency. More than 441,000 infants and toddlers received Part C early intervention services in the 2022–23 year.¹ If your child is under 3 and you have developmental concerns, ask your pediatrician or your state’s early intervention program about Part C rather than the school district.

IDEA vs. Section 504

Families often hear about “504 plans” alongside IEPs, and the two are easy to confuse. IDEA is a federal education statute that provides funding and requires a detailed IEP with measurable goals and specialized instruction. Section 504 of the Rehabilitation Act is a civil rights law that prohibits disability discrimination in any program receiving federal funding and uses a broader definition of disability. A child who does not qualify for an IEP under IDEA’s 13 categories may still qualify for accommodations under a 504 plan.¹⁷

The practical difference matters. An IEP can include modified curriculum, specialized interventions, and a range of related services, developed and monitored by a team that includes a certified special education teacher. A 504 plan focuses on removing barriers through accommodations such as extended testing time or preferential seating, and it does not carry federal funding. Both require schools to provide FAPE and both include procedural safeguards for families.¹⁸

If you suspect a disability is affecting your child’s learning, the first step is a written request for a full evaluation under IDEA. From there, the timelines, the team, and your rights as a parent all follow the process the law lays out.
