Prior Written Notice: The IDEA Right Schools Rarely Explain

Prior written notice (PWN) is a legal document schools are required to give you whenever they propose or refuse to take action related to your child’s identification, evaluation, educational placement, or the provision of FAPE. Most parents have never received one and don’t know they can request one. This guide explains what it is and when you should ask for it.

What PWN Must Include

Prior written notice is not just a form. It is a legally required document with specific components. If the school provides you with something labeled PWN but it doesn’t contain all of the following elements, it may not satisfy the requirement.

✓Description of the action proposed or refused. What exactly is the school doing, or declining to do?
✓Explanation of why the school is proposing or refusing the action. The reasoning must be spelled out, not just implied.
✓Description of each evaluation procedure, assessment, record, or report used to make the decision. You have the right to know what data they relied on.
✓Description of other options the IEP team considered and the reasons those options were rejected. This element is frequently missing from school-generated PWNs.
✓Description of any other factors relevant to the school’s proposal or refusal.
✓Statement of procedural safeguards available and how to obtain them.

When to Request Prior Written Notice

The situations below are among the most common times parents should ask for PWN. In many of these cases, the school is required to provide it automatically, but in practice, many don’t. Asking for it in writing creates a paper trail and forces the school to document its reasoning.

The school refuses your evaluation request. This is a textbook PWN situation, and schools frequently skip it.
The school proposes to change your child’s placement, including moving them to a more restrictive setting or removing them from a current service.
The school reduces services at annual review. Any change in services requires PWN, whether the change is an increase or a reduction.
The school refuses to add a service you requested at an IEP meeting. If you asked for speech therapy and the team said no, that refusal should be documented in a PWN.
The school finds your child ineligible for special education. An ineligibility determination is a refusal to identify and requires PWN.

How to Request Prior Written Notice

You do not need to use legal language or cite IDEA chapter and verse to request PWN. What matters is that your request is in writing and specific.

You do not need to use specific legal language. A clear written request is sufficient.
Submit a written request that says something like: “I am requesting prior written notice for [the specific action the school proposed or refused]. Please provide it within a reasonable time.”
The school must respond. No response is itself a procedural violation, and silence strengthens your documentation if you later need to file a state complaint.

Send your request by email so you have a timestamped record. Keep copies of everything.

How to Use PWN as an Advocacy Tool

A well-written PWN tells you exactly what data the school used to make a decision. That makes it much easier to challenge the decision, because you know what evidence they relied on and what they considered and rejected. If the PWN lists thin or irrelevant data as the basis for a significant decision, that gap is your entry point.

Compare the PWN to the IEP and evaluation data. Do the documents line up? Is the decision actually supported by the evidence cited?
Look for decisions not supported by the data they cite. A school that refuses a reading evaluation but cites only classroom grades, rather than any diagnostic reading assessment, has documented its own inadequate process.
Use the “other options considered” section to identify what the school chose not to offer and why. This section often reveals how narrowly the team was thinking and what alternatives exist that you can advocate for at a future meeting.
Save every PWN you receive. Over time, they create a record of the school’s reasoning and decision-making that can be critical in a dispute resolution proceeding.

What is prior written notice in special education?

Prior written notice (PWN) is a document schools must provide whenever they propose or refuse to initiate or change the identification, evaluation, educational placement, or provision of a free appropriate public education (FAPE) for your child. It must include a description of the action proposed or refused, the reason for the decision, a description of other options the team considered and why they were rejected, a description of the evaluation procedures or data used to make the decision, and information about where you can get assistance in understanding your rights.

When should the school send me prior written notice?

The school should send PWN any time they propose or refuse a significant action: proposing an initial evaluation, refusing your request for an evaluation, proposing a specific eligibility category, proposing or refusing to change placement, proposing a change to services, or refusing to add services you’ve requested. In practice, many schools skip PWN for refusals, which is a procedural violation of IDEA.

What can I do if the school made a decision without giving me prior written notice?

Failure to provide PWN is a procedural violation of IDEA. You can document the violation in writing, request a copy of the PWN retroactively, raise it as a procedural violation in a state complaint or due process hearing, and use it as evidence that the district is not following IDEA’s procedural safeguards. Procedural violations can form the basis of a state complaint even without a substantive denial of FAPE.
