PWN turns a hallway answer into a paper trail.
The school can disagree with you. What it cannot do is make important special education decisions without explaining the action, the reason, and the evidence in writing.
meeting
required record
evidence
Use PWN when the decision matters later.
A strong paper trail is calm, specific, and tied to the school decision you are trying to understand.
What did the school propose, change, or refuse?
What data, reports, or options did the team rely on?
The notice becomes the record if the disagreement continues.
What it is
Prior Written Notice is a written explanation the school district must give you whenever it proposes to start or change, or refuses to start or change, your child's identification, evaluation, educational placement, or the provision of a free appropriate public education (FAPE). This is one of your core rights under the federal special education law, IDEA, at 34 CFR 300.503.
It applies to refusals too. If you ask for an evaluation, a service, or a placement change and the school says no, that no must come with a Prior Written Notice explaining why.
Why it matters
A Prior Written Notice forces the district to put its reasoning in writing, which protects you in any later disagreement. If a decision was made verbally at a meeting, you can request the notice in writing afterward.
Read a PWN like an evidence receipt.
The letter is useful only if it tells you what happened, why, and what records the school relied on. Use this four-part audit before you decide whether the notice answers your question.
What did they do?
Find the exact action the school proposed or refused.
Why did they do it?
The notice should explain the reason, not just repeat the conclusion.
What did they rely on?
Look for evaluations, reports, records, and options considered.
What is missing?
If a piece is vague or absent, ask for the notice to be clarified.
The seven things every notice must contain
Open each card as you read a notice. By law, every Prior Written Notice must include all seven of these (34 CFR 300.503(b)).
The action
A description of the action the school proposed or refused.
The reason
An explanation of why the school proposed or refused it.
The evidence
A description of each evaluation, assessment, record, or report the school used as the basis for the decision.
Your safeguards
A statement that you are protected by the procedural safeguards, and how to get a copy of them.
Help sources
Sources you can contact for help understanding your rights.
Other options
A description of the other options the IEP team considered and why each was rejected.
Other factors
A description of any other factors relevant to the school's decision.
The notice must be written in language understandable to the general public, and provided in your native language or other mode of communication unless that is clearly not feasible (34 CFR 300.503(c)).
The federal rule is the floor. Timing is state-specific.
The federal rule says the notice must come a reasonable time before the school acts, and federal law does not define a specific number of days.
California: reasonable time, with no fixed day count.
California follows the federal reasonable-time standard. Education Code section 56500.4 requires the notice but does not set a specific number of days.
California also treats graduation with a regular diploma as a change of placement that requires this notice (Education Code section 56500.5).
Ask whether the notice arrived before the school acted.
If the timing feels rushed, ask what made it a reasonable time in your child's situation.
Texas: five school days for most PWN, and 15 school days for some evaluation refusals.
Texas requires the notice at least five school days before the school proposes or refuses the action, unless you agree to a shorter timeframe (19 Texas Administrative Code section 89.1075).
If you submit a written request for a full initial evaluation and the district refuses, it must give you Prior Written Notice of that refusal by the 15th school day after receiving your request (19 Texas Administrative Code section 89.1011).
Count school days, not calendar days, unless you agreed to a shorter timeframe.
For a refused written full initial evaluation request, check the 15-school-day response clock.
If the notice is missing or incomplete
A missing or incomplete Prior Written Notice is a procedural problem you can raise. It can also be evidence that the school kept you from meaningfully participating in your child's plan. If you disagree with the action described in a notice, you have the right to challenge it, including through your state's dispute and due process options.
Ask for the decision in writing.
- After any verbal decision at a meeting, ask for it in a Prior Written Notice, in writing.
- Check any notice you already have against the seven required items above.
- Keep every notice in one place. They are the paper trail that wins disagreements.
If the school says no out loud
"Please put that refusal in Prior Written Notice so I can understand the reasons and the data the team relied on."
If the notice is vague
"Can you identify the evaluations, records, and other options the team considered? I need the notice to include those pieces."
If you need help reading it
"Please send the procedural safeguards and the contact information for help understanding my rights."
