Quick Answer
Prior written notice (PWN) is a written document the school must provide whenever it proposes or refuses to take any action related to your child's IEP — including changes to evaluation, placement, or services. It must explain what action is being taken or refused, why, and what alternatives were considered. PWN creates a paper trail and is legally required under IDEA at 34 CFR 300.503.
Prior written notice (PWN) is a document the school must provide whenever it proposes or refuses to take any action regarding your child's identification, evaluation, placement, or services. It must explain what is being proposed or refused, why, and what alternatives were considered. It is required under IDEA at 34 CFR 300.503 — and it is one of the most powerful tools a parent can use.
Most parents never ask for it. Schools are not required to hand it over unless they're making a decision — but you can demand it any time the district says no to something you've requested.
What Is Prior Written Notice?
Prior Written Notice (PWN) is a written document the school must provide to you whenever they propose or refuse to change something about your child's special education. It is required by federal law under the Individuals with Disabilities Education Act (IDEA) (34 CFR 300.503).
PWN is not optional. It is not a courtesy. It is a legal requirement. Every time the school says "yes" or "no" to something related to your child's identification, evaluation, placement, or services, they owe you a written explanation.
Think of PWN as the school's homework. They have to show their work — not just give you the answer.
When Schools Must Provide PWN
Under 34 CFR 300.503(a), the school must provide PWN whenever it:
- Proposes to initiate or change the identification, evaluation, placement, or provision of FAPE for your child
- Refuses to initiate or change the identification, evaluation, placement, or provision of FAPE for your child
In plain language, that means any time the school says yes or no to something that affects your child's special education. Here are common situations that require PWN:
| Situation | PWN Required? |
|---|---|
| You request an evaluation and the school agrees | Yes |
| You request an evaluation and the school refuses | Yes |
| The school proposes adding a service | Yes |
| The school proposes removing a service | Yes |
| You request a change in placement | Yes — whether granted or denied |
| The school changes your child's goals | Yes |
| The school exits your child from special education | Yes |
| You request an accommodation and the school says no | Yes |
| The school reduces service hours | Yes |
The 7 Required Elements of PWN
Under 34 CFR 300.503(b), every PWN must include these seven specific elements. If any of them are missing or vague, the notice does not meet federal requirements.
- A description of the action — What exactly is the school proposing or refusing to do?
- An explanation of why — What is the school's reasoning? Not just "the team decided" — the actual reason.
- A description of each evaluation, assessment, record, or report used — What data did the school rely on to make this decision?
- A statement of procedural safeguards — Your rights, including how to access a full copy of the procedural safeguards notice.
- Sources for parents to get help — Contact information for organizations that can help you understand the notice (such as your state's Parent Training and Information Center).
- Other options considered — What alternatives did the school consider, and why were they rejected?
- Other relevant factors — Any other information that is relevant to the decision.
How to Use PWN as Leverage
PWN is not just a form. It is a decision-forcing mechanism. Here is why it is so powerful:
1. It creates a paper trail
Every PWN is a written record of what the school decided and why. If you later need to file a complaint, request mediation, or go to due process, PWN documents become your evidence. Verbal agreements and meeting conversations are hard to prove. PWN is on paper.
2. It forces the school to commit to reasoning
Many IEP decisions are made with vague justifications — "the team feels..." or "we don't think it's necessary right now." When the school has to write down their reasoning and cite the data they relied on, weak decisions often fall apart. A decision that sounds reasonable in a meeting can look indefensible in writing.
3. It gives you time to respond
You are never required to agree with a PWN on the spot. You can take it home, review it, consult with an advocate or attorney, and respond in writing. The school cannot implement a change before giving you PWN and a reasonable opportunity to respond.
4. It exposes procedural violations
If the school makes a decision without providing PWN — or provides PWN that is missing required elements — that is a procedural violation of IDEA. Procedural violations can support a finding that your child was denied FAPE (Free Appropriate Public Education), especially if the violation impeded the parent's right to meaningful participation.
How to Request PWN (Sample Language)
If the school made a decision without providing PWN — or if you want to create a paper trail for a refusal — send a request in writing. Here is sample language you can adapt:
Dear [Case Manager / Special Education Director],
I am writing to request Prior Written Notice (PWN) as required under 34 CFR 300.503 regarding the following decision(s) made at/about my child's IEP:
[Describe the specific decision — e.g., "The team's decision to reduce speech therapy from 3 times per week to 2 times per week" or "The school's refusal of my request for an independent educational evaluation at public expense."]
Please provide the PWN including all seven required elements under 34 CFR 300.503(b): the action proposed or refused, the reasons why, the evaluation data relied upon, my procedural safeguards, sources for help understanding the notice, other options considered, and other relevant factors.
Thank you for your attention to this federal requirement.
[Your name]
[Date]
Red Flags in Your PWN
Not all PWN is created equal. Here are the most common problems to watch for:
- "The team decided..." — Who is "the team"? What data did the team review? A PWN that relies on a collective noun without citing specific data does not meet the requirement to describe the evaluations and records used.
- "Not appropriate at this time." — Why? What would make it appropriate? What data supports this? Timing-based refusals without data are a red flag.
- Missing element #6 (alternatives considered). — If the school did not list other options it considered and why they were rejected, the PWN is incomplete. This is the most commonly omitted element and the easiest to challenge.
- Boilerplate language. — If the PWN reads like it was copied from a template — with no specific references to your child, your child's data, or your specific request — it likely does not meet the individualized requirements of IDEA.
- No data cited. — The PWN must describe the evaluations, assessments, records, or reports the school relied on. If none are named, the school cannot demonstrate that the decision was data-driven.
- Retroactive PWN. — If the school implements a change first and provides PWN after the fact, that violates the "prior" in Prior Written Notice. The notice must come before the action, not after.
What to Do If You Never Received PWN
If the school changed your child's services, placement, goals, or evaluation status without providing PWN, here is what to do:
- Request it in writing immediately. Use the sample letter above. Cite 34 CFR 300.503 and ask for the PWN including all seven required elements.
- Document the timeline. Note when the change happened and when (or if) you received notice. The gap between the action and the notice is your evidence of a violation.
- Send a follow-up if they don't respond. If the school does not provide PWN within a reasonable time (7-10 school days), send a follow-up email referencing your original request.
- File a state complaint. If the school refuses to provide PWN or provides inadequate notice, you can file a complaint with your state department of education. Failure to provide PWN is a clear-cut procedural violation — these complaints are relatively straightforward to win.
- Consider requesting an Independent Educational Evaluation (IEE). If the school made a decision based on their evaluation data and refused to explain it in writing, you may want an outside expert to review the situation.
Your PWN Checklist
Use this checklist every time you receive PWN from your child's school:
- Does it describe the specific action? — Not a vague summary, but the exact change being proposed or refused.
- Does it explain WHY? — A real reason, not "the team decided" or "not appropriate at this time."
- Does it cite specific data? — Evaluation reports, progress data, assessments, or records — by name, not generically.
- Does it include your procedural safeguards? — A statement of your rights and how to access the full notice.
- Does it list sources for help? — Contact information for your state's PTI or other parent support organizations.
- Does it list alternatives considered? — What else the school thought about and why those options were rejected.
- Does it include other relevant factors? — Any additional information the school considered.
- Was it provided BEFORE the action? — Not after. Not at the meeting. Before.
- Is it in your primary language? — If English is not your dominant language, the notice must be translated or interpreted.

Arizona
Arizona's prior written notice (PWN) requirement is grounded in both federal IDEA (34 CFR 300.503) and Arizona law (A.R.S. § 15-766). Before the district proposes or refuses to initiate any change in identification, evaluation, educational placement, or provision of FAPE, you must receive written notice explaining the proposed action, the reasons, and the data that informed the decision. This requirement applies in Arizona to traditional districts, charter schools, and accommodation schools equally (A.R.S. § 15-761).
In Arizona, the PWN is also your gateway to formal dispute resolution. If you disagree with the decision documented in a PWN, you can request mediation through ADE ESS, file a state complaint (resolved within 60 days), or request a due process hearing through the Office of Administrative Hearings (OAH). Remember: Arizona law requires the public educational agency to bear all due process hearing costs (A.R.S. § 15-766(E)) — requesting PWN and acting on it carries no financial cost to you.
