What is prior written notice?

Prior written notice is the school’s written explanation after it proposes or refuses to change identification, evaluation, placement, or FAPE. You do not write it. The school does, and you use it to understand the decision.

This article explains federal special education law (IDEA). Your state may have its own deadlines, forms, and complaint rules. Check your school's procedural safeguards notice for state-specific details.

Quick answer

Prior written notice, or PWN, is a document the school must give you after it proposes or refuses to change your child’s identification, evaluation, placement, or services. It comes after the decision, not before. If the team says no at a meeting, or proposes a major change, ask when you will receive PWN if the school does not hand it to you then.

What this means for parents

PWN is not a form you fill out and not the same as the procedural safeguards booklet you receive once a year. It is the school’s written record of one specific proposal or refusal.

The school must provide PWN when it proposes or refuses to change identification, evaluation, placement, or FAPE.
The notice should explain what the school decided, why, what data it used, and what other options were considered.
It should also tell you where to get help understanding your rights and how to obtain a copy of procedural safeguards.
Read PWN carefully before you agree, disagree, request another meeting, or consider a state complaint or due process.

What to do after the team decides

PWN documents a decision that already happened. Your job is to make sure you receive it and that it answers your questions.

If the team refuses your request, say clearly what was refused and ask for prior written notice explaining the refusal.
If the team proposes a change, ask when prior written notice will be sent and what exactly is being proposed.
When you receive PWN, check that it lists the action, the school’s reasons, the evaluation data or records used, and other options the team considered.
If PWN is missing, vague, or late, follow up in writing and keep a copy for your records.

Simple parent script

After the team says no

At today’s meeting, the team refused my request for [specific request]. Please provide prior written notice explaining that refusal. The notice should describe the action refused, the reasons and evaluation data the team used, other options considered, and information about my procedural safeguards.

If you never received PWN

On [date], the team refused my request for [specific request], but I have not received prior written notice. Please send PWN as soon as possible, including the reasons for the refusal, the data the team relied on, and other options that were considered.

Common mistakes to avoid

Treating a verbal “no” at a meeting as enough, without asking for written notice.
Confusing prior written notice with the annual procedural safeguards notice.
Assuming PWN is something parents draft or submit to the school.
Agreeing to a major change or walking away from a refusal without reading PWN first.

When to get more help

Consider getting help when the school will not provide PWN after a refusal or proposal, the notice leaves out reasons or data, the decision affects placement or services in a major way, or you need to decide quickly whether to file a state complaint or request due process.
