How Long Does an IEP Evaluation Take?

Q: When does the IEP evaluation timeline start?

The evaluation timeline starts when the school receives your signed consent for evaluation, not when you made the request. Schools must first provide Prior Written Notice agreeing to evaluate, then give you a consent form. The 60-day (or 90-day in NC) clock begins on the date your signed consent is received by the school.

Q: Does summer break pause the IEP evaluation timeline?

It depends on the state. In North Carolina, the 90-day timeline runs on calendar days and does not pause for summer unless mutually agreed in writing by the parent and school. If your child's consent was signed in spring and the timeline extends into summer, the school is still legally required to meet the deadline. Verbal agreements about delays do not count.

Federal law gives schools 60 calendar days from parental consent to complete an IEP evaluation and hold an eligibility meeting. North Carolina extends that to 90 calendar days. The clock starts the day your signed consent reaches the school, not the day you made the request. Most families don't know this distinction, which means they often can't tell when a school is running late.

The Short Answer: 60 Days Federal, 90 Days in NC

Under IDEA, the federal default is 60 calendar days from receipt of parental consent for evaluation to completion of the evaluation and the eligibility meeting. States can set their own timelines as long as they are consistent. North Carolina chose 90 calendar days. South Carolina follows the 60-day federal standard.

State	Evaluation Timeline	Clock Starts
Federal (IDEA default)	60 calendar days	Date school receives signed consent
North Carolina	90 calendar days	Date school receives signed consent
South Carolina	60 calendar days	Date school receives signed consent

Important: The timeline is measured in calendar days, not school days. Summer break, winter break, and holiday periods count unless a written mutual agreement extends the timeline.

The Full Timeline, Step by Step

The evaluation timeline is one piece of a larger sequence. Here is how the entire process plays out from the moment you request an evaluation to the day your child has an active IEP.

No fixed deadline

You submit a written evaluation request

The timeline does not start here. The school must respond with Prior Written Notice (PWN) indicating whether they agree to evaluate. No federal law sets a hard deadline on this response, but most states require a reasonable timeframe. In practice, expect 5 to 15 school days.

Clock starts here

You sign and return consent for evaluation

The 60-day (or 90-day in NC) evaluation timeline starts the day the school receives your signed consent, not the day you mailed it. Hand-deliver and get a receipt, or email and keep a timestamp. This date matters if you ever need to file a complaint.

Within the 60 or 90-day window

School conducts the evaluation

Assessments are scheduled and completed. Depending on how many specialists are involved, this phase can take 4 to 10 weeks. You can submit written parent input at any time during this phase. You are also entitled to see all evaluation reports before the eligibility meeting.

Before deadline expires

Eligibility meeting is held

The school must hold the eligibility meeting, review the evaluation data, and determine whether your child qualifies for special education, all before the deadline. The meeting itself must occur before the timeline window closes, not just be scheduled.

Within 30 days of eligibility

IEP is developed (if eligible)

If your child is found eligible at the eligibility meeting, IDEA requires that the initial IEP be developed and a placement decision made within 30 days of the eligibility determination. In practice, many schools schedule the eligibility meeting and IEP development meeting together or in close sequence.

Total realistic timeline in NC: From evaluation request to an active IEP typically takes 3 to 5 months. The 90-day evaluation window plus the 30-day IEP development period accounts for about 4 months. Add the time between your request and consent, and the full process routinely runs to 5 months for families who move quickly at every step.

What Does NOT Count Toward the Deadline

Two situations legitimately stop the clock:

Parent-caused delays. If you are unavailable or request a postponement of a scheduled meeting, the days attributable to your unavailability may not count. Schools sometimes use this provision loosely. Any agreed-upon extension should be documented in writing.
Child enrolled after the school year ends. If a child first enrolls in a school district and the timeline would expire over the summer, the 60-day window may be suspended. This applies specifically to initial evaluations for children new to the district.

What does not stop the clock: holidays, spring break, teacher training days, staff scheduling issues, difficulty reaching a specialist, or the school claiming they are busy. These are operational problems, not legal exceptions. The deadline applies regardless.

What to Do When the School Misses the Deadline

Schools miss evaluation deadlines more often than families realize, and most parents do not know they can hold the school accountable.

Your options when a deadline is missed:

File a state complaint. In North Carolina, file with the NC Department of Public Instruction, Exceptional Children Division. In South Carolina, file with the SC Department of Education. The state must investigate and respond within 60 days. A finding of a procedural violation can result in corrective action, compensatory services, or other remedies.
Request mediation. A lower-stakes process than due process, mediation can be used to resolve disputes including missed timelines.
File for due process. If the delay resulted in your child losing educational benefit, you can seek compensatory services through due process.

Before you act: Confirm your consent date in writing. Schools sometimes dispute when they actually received your consent. If you hand-delivered consent, note the date and who you gave it to. If you mailed it, keep the tracking receipt. If you emailed it, your sent folder is your record.

Reevaluation Timeline

Once your child has an IEP, IDEA requires a reevaluation at least every three years (the triennial evaluation). The same 60-day (or 90-day in NC) timeline applies to reevaluations after consent is received. Parents can also request a reevaluation at any time, and the school must respond with Prior Written Notice and either agree to evaluate or explain why they are declining.

One difference from initial evaluations: for reevaluations, the school may determine that no new assessments are needed and propose relying on existing data. You must consent to this approach or can request new testing. If the school proposes to use existing data only and you disagree, put your disagreement in writing and request specific assessments.

Is the School Running Behind?

If you are approaching or past the evaluation deadline and the school has not scheduled your child's eligibility meeting, contact Meghan. A single consultation can clarify your options and help you document the timeline correctly before filing a complaint.
