What Is Prior Written Notice?
Prior Written Notice is a formal written document that schools are legally required to provide to parents under IDEA § 300.503 any time the school proposes or refuses to initiate or change the identification, evaluation, educational placement, or provision of FAPE for a child with a disability.
In plain language: whenever the school wants to make a significant change to your child's special education program — or when you request a change and they say no — they must give you a written document explaining exactly what they are proposing or refusing, why, and what evidence supports that decision.
PWN is not optional. It is not a courtesy. It is a federally mandated procedural safeguard that exists specifically to ensure parents have the information they need to meaningfully participate in decisions about their child's education — and to create an official record when disputes arise.
📖 The Legal Requirement: IDEA § 300.503
IDEA requires that schools provide PWN "a reasonable time before the public agency proposes or refuses to initiate or change the identification, evaluation, or educational placement of the child or the provision of FAPE to the child." The notice must be written in language understandable to the general public and provided in the native language of the parent unless clearly not feasible.
When Must the School Provide PWN?
The school is required to provide Prior Written Notice in a wide range of situations. Many parents don't realize how broadly this obligation applies — it is not limited to formal IEP meetings or major placement decisions.
When the school proposes an evaluation
Before conducting an initial evaluation or reevaluation, the school must provide PWN describing what they intend to evaluate, why, and what assessment tools will be used. Parents must also provide informed written consent before the evaluation begins.
When the school refuses to evaluate
If you request an evaluation and the school declines, they must provide PWN explaining why they are refusing, what data they reviewed in making that decision, and what other options they considered. A verbal "we don't think he needs an evaluation" is not legally sufficient.
When the school proposes a placement change
Any time the school proposes moving your child to a more or less restrictive setting — from general education to a resource room, from a resource room to a special education classroom, or any other placement change — PWN is required before the change is made.
When the school refuses a placement change you requested
If you ask the school to move your child to a different setting and they say no, that refusal must be documented in a PWN with a full explanation of why the current placement is appropriate and what the school considered before deciding.
When the school proposes changes to services
Adding, reducing, or eliminating related services — speech therapy, OT, PT, counseling, aide support — all require PWN. This includes the end-of-year transition when services are reduced or changed for the following school year.
When the school refuses services you requested
If you ask for a specific service or accommodation and the school declines, their refusal must be documented in writing with a clear explanation of why they believe the current program provides FAPE without the requested service.
What Must PWN Contain?
IDEA specifies exactly what information Prior Written Notice must include. A PWN that is missing required elements is legally deficient — and that deficiency can be the basis for a procedural complaint. The required elements under 34 CFR § 300.503(b) are:
| Required Element | What It Means in Practice |
|---|---|
| Description of the proposed or refused action | A clear statement of exactly what the school is proposing to do or declining to do — not vague language like "continue current programming" but specific changes or refusals |
| Explanation of why | The school must explain the reasons for the proposal or refusal — not just "we believe this is appropriate" but what specific factors led to the decision |
| Description of each evaluation procedure, assessment, record, or report used | Every piece of data the school relied on in making the decision must be identified — test scores, observation reports, teacher input, progress data |
| Description of other options considered and reasons they were rejected | The school must document what alternatives they considered before landing on the proposal or refusal — this is one of the most frequently missing and most important elements |
| Description of other relevant factors | Any other information that influenced the decision must be disclosed |
| Sources for obtaining assistance in understanding IDEA | The PWN must include information about where parents can get help understanding their rights — typically the state Parent Training and Information Center |
⚠️ "We Discussed This at the IEP Meeting" Is Not a PWN
One of the most common misconceptions is that a verbal discussion at an IEP meeting — or even meeting notes — substitutes for Prior Written Notice. It does not. PWN must be a separate written document that meets all the requirements of § 300.503. If the school makes a proposal or refusal at an IEP meeting and does not follow up with a written PWN that contains all required elements, the school has violated IDEA's procedural requirements. You have the right to request the PWN in writing after any meeting where a proposal or refusal was made.
How Parents Can Use PWN as an Advocacy Tool
Most parents think of PWN as something the school provides to them. But PWN is equally powerful as something parents request from the school — and requesting it strategically is one of the most effective tools in the IEP parent's toolkit.
Request PWN When the School Denies Anything
Any time a school declines a request you make — for an evaluation, a service, a placement change, an accommodation — your immediate response should be to request Prior Written Notice in writing. The act of requesting PWN accomplishes several things simultaneously: it forces the school to document their reasoning formally, it creates an official record of the denial, it makes a verbal "no" legally insufficient, and it often causes schools to reconsider their position when they realize they must justify it in writing with data.
Many parents report that simply requesting PWN in writing results in the school reversing a denial — because when administrators have to formally document why they are refusing a service, the justification often doesn't hold up.
Use PWN to Build a Paper Trail
If you are heading toward a dispute with the school — or if you believe you may need to file a state complaint or request due process in the future — a well-documented set of PWNs is essential evidence. Each PWN the school provides is a formal record of what was proposed or refused, when, and why. Gaps in the PWN record — situations where changes were made without required notice — are themselves procedural violations that can support a complaint.
Analyze PWN for Missing Elements
When you receive a PWN, review it against the required elements listed above. Ask specifically: did the school document every alternative they considered and why they rejected it? Did they identify all the data they relied on? A PWN that says "we considered placement in general education but determined the current placement is more appropriate" without explaining what data supported that determination is legally inadequate. You can request a revised, compliant PWN if the original is deficient.

Start Free — No Credit Card Required ›How to Request PWN From the School
Requesting Prior Written Notice is straightforward — but it must be done in writing to create a clear record. A verbal request can be ignored or forgotten. A written request creates a paper trail and starts a clock.
Your request does not need to be complicated. A simple email or letter that includes the following is sufficient:
- Your child's name and the date
- A reference to the specific proposal or refusal you are requesting PWN for
- A citation to IDEA § 300.503 and your right to Prior Written Notice
- A request for the PWN to be provided within a reasonable time
Send the request by email so you have a timestamped record. Address it to the special education director or IEP coordinator, not just the classroom teacher.
💡 What to Do If the School Ignores Your PWN Request
If you request Prior Written Notice in writing and the school does not provide it within a reasonable time — typically 10 business days is a reasonable standard — you have grounds for a procedural complaint with your state education agency. Failure to provide required PWN is a violation of IDEA's procedural safeguards. File a state complaint, which is free, requires no attorney, and must be investigated within 60 days. The complaint itself often prompts the school to comply immediately.
PWN vs. Consent: What's the Difference?
Parents sometimes confuse Prior Written Notice with consent. They are related but distinct rights. PWN is the school's obligation to inform you in writing about proposals and refusals. Consent is your right to agree or disagree before certain actions are taken. The school must provide PWN before conducting an initial evaluation — and then separately obtain your informed written consent before proceeding. PWN alone does not authorize the school to act. Similarly, you can consent to an evaluation while still having the right to receive PWN about how that evaluation will be conducted.
PWN and the IEP Amendment Process
After an IEP is written and signed, changes to the IEP require either a full IEP team meeting or, in some states and under some circumstances, a written amendment agreed to by the parents without a meeting. In either case, if the change involves a proposal or refusal that triggers PWN requirements — a change in placement, services, or identification — PWN must be provided. An IEP amendment that reduces services without accompanying PWN is a procedural violation.
