An Individualized Education Program, or IEP, moves through four required stages: referral, evaluation, eligibility, and a written plan reviewed at least once a year. Federal law sets the outer limits on that timeline — public schools must complete an evaluation within 60 days of a parent's written consent, according to the U.S. Department of Education's IDEA site, though some states set shorter windows.
When does a school start the IEP process?
The process opens one of two ways. A parent can ask, in writing, for an evaluation by contacting a child's teacher, principal, or the district's special education director. Or a school can recommend one after a teacher's classroom observations or the results of a screening test. Either path requires the school to get informed, written parental consent before any formal testing begins — the district cannot evaluate a child without it.
This first step only opens the door. It doesn't guarantee services. A child has to be formally evaluated and found eligible under one of IDEA's disability categories before a school is required to write a plan.
What counts as a qualifying disability?
Federal regulation lists thirteen categories a child can qualify under, including specific learning disability, speech or language impairment, autism, emotional disturbance, other health impairment, and — for children ages three to nine — a general developmental delay. Meeting one of those labels isn't enough on its own. The regulation is specific that a child only counts as having a disability under the law if the condition means the child "needs special education and related services" — a diagnosis without an educational impact doesn't trigger an IEP.
That distinction matters for families: a school can acknowledge a diagnosis and still conclude, after evaluation, that a child doesn't need specially designed instruction to access the curriculum. Parents who disagree with that conclusion have the right to challenge it, including by requesting an evaluation the school doesn't pay for initially and then disputing the results.
How long can the evaluation take?
Once a parent signs consent, the school has to complete the evaluation "within 60 days of receiving parental consent," or within whatever shorter timeframe the state has set, according to the Center for Parent Information and Resources, a federally funded technical assistance hub. The evaluation itself is supposed to draw on multiple tools and sources — not a single test score — before anyone decides whether a child qualifies.
The law doesn't set a fixed number of days for the eligibility meeting that follows, but parents are entitled to sit in on it and hear the results explained. If a family disagrees with the school's findings, they can request an independent evaluation, and children found eligible are reevaluated at least once every three years going forward.
Who sits on the IEP team?
Federal regulations spell out exactly who has to be in the room. The required IEP team includes the child's parents, at least one of the child's regular education teachers if the child takes part in general education, at least one special education teacher or provider, a school representative qualified to supervise special education instruction, someone who can interpret the evaluation results, and — when it's appropriate — the student. Related-service providers, like a speech therapist or school psychologist, can join when their expertise is relevant.
No one on that list outranks the others. Parents are meant to be equal participants, not guests at a meeting where decisions have already been made.
What has to be in the IEP document?
The IEP itself isn't a free-form document — federal regulation lists what has to be in it, and a plan missing these pieces isn't compliant. According to the federal regulation governing IEP contents, every plan must include:
- A statement of the child's current academic and functional performance
- Measurable annual goals, both academic and functional
- How and when progress toward those goals will be measured and reported
- The specific special education and related services the child will receive
- How much time the child will spend outside general education classrooms, and why
- Any accommodations needed for standardized testing
- The start date, frequency, location, and duration of every service listed
Once a student turns 16, the plan also has to include transition goals and services aimed at life after high school — further education, a job, or independent living.
How often does the plan get reviewed?
At least once a year. A child's IEP has to be reviewed on that schedule to check whether the goals are being met and to revise the plan if they're not. That annual review is separate from the three-year reevaluation cycle, which asks the bigger question of whether the child still qualifies for services and whether the disability category still fits.
Parents don't have to wait for the scheduled review if something changes — a move to a new school, a diagnosis, a stretch of falling grades. Any team member, including a parent, can request an IEP meeting sooner. The annual review and the three-year reevaluation aren't the same meeting and shouldn't be treated as interchangeable: one asks whether the current goals are working, the other asks whether the child still qualifies for services at all.
What if the school and family don't agree?
Disagreement inside the IEP process is common enough that the law builds room for it. Because every parent on the team has equal standing, a family can decline to sign a proposed plan, request additional data before a decision is finalized, or ask for time to review draft goals rather than approving them on the spot in the meeting. The formal mediation and complaint procedures IDEA provides once informal disagreement doesn't resolve things are a distinct process with their own rules, outside the scope of this guide — a family facing a real dispute should ask the district's special education office directly about those options.
What can a family actually do with this?
The practical takeaway is that every stage of this process runs on a clock, and the clock starts when a parent puts a request in writing — not when they mention a concern in passing at pickup or in an email that never gets a reply. Keeping a dated, written record of every request, consent form, and meeting invitation gives a family something concrete to point to if a deadline slips or a meeting keeps getting rescheduled.
None of this requires special expertise to start. It requires knowing the sequence exists, roughly how long each stage is supposed to take, and that a parent's signature — or refusal to sign — is one of the few points in the process where a family has direct, immediate leverage. The rest is largely a matter of showing up to a meeting where, by law, no one at the table outranks a parent's knowledge of their own child.
