IEP & IDEA Timelines Every Parent Should Know

IDEA runs on deadlines. Missing one can be a violation of your child’s rights — so it pays to know the clock. (Exact days vary by state; check your state’s page.)

Evaluation timeline

After you give written consent, the school generally must complete the initial evaluation within 60 days (many states use 60; some differ). This determines whether your child is eligible for special education.

IEP development

If your child is found eligible, the team must hold a meeting and have an IEP in place within 30 days of the eligibility determination in most states. Services should begin promptly after you consent.

Annual review

The IEP team must review the IEP at least once a year to check progress and update goals and services. You can request a review sooner any time you have concerns.

Reevaluation

A full reevaluation happens at least every three years (the “triennial”) to decide if your child still qualifies and what they need — unless you and the school agree it isn’t necessary.

Notice and dispute deadlines

• Prior written notice: the school must notify you a set number of days before changing identification, evaluation, placement, or services.
• Records: you can request your child’s records and must receive them before any meeting or hearing.
• Due process: there’s a limited window (commonly two years) to file after a disagreement.
