Prior Written Notice: What It Is, What to Do When You Get One

A letter arrives from the school. It’s dense, formal, and full of legal language. Somewhere near the top, in bold or italics, are the words “Prior Written Notice.”

What happens next matters. A lot.

What Is a Prior Written Notice?

A Prior Written Notice (PWN) is a written document that a school district must provide to parents whenever it proposes to initiate or change — or refuses to initiate or change — the identification, evaluation, or educational placement of a student with a disability, or the provision of Free Appropriate Public Education (FAPE).

In plain terms: any time the school wants to do something significant with your child’s special education, or any time they’re saying no to something you’ve requested, they must tell you in writing. In advance.

This is not a courtesy. It is a legal requirement under IDEA — specifically, 34 CFR 300.503.

What Must a PWN Include?

A legally compliant PWN must contain all of the following:

1. A description of what the school proposes or refuses to do. Clear, specific, actionable — not vague.
2. An explanation of why the school is proposing or refusing this action. The reasoning behind the decision.
3. A description of each evaluation procedure, assessment, record, or report the school used as a basis for its decision. The evidence.
4. A description of any other options the IEP team considered and the reasons why those options were rejected. The alternatives they looked at.
5. A description of any other factors relevant to the school’s decision.
6. A statement that parents have procedural safeguards available and how to obtain them.
7. Sources for parents to contact to obtain assistance in understanding the PWN.

If the PWN you received is missing any of these elements, it is legally deficient. You can note this in writing and request a compliant PWN.

Common Situations Where You’ll Receive a PWN

The school wants to change your child’s placement

Perhaps they’re proposing to move your child from a general education classroom to a more restrictive setting, or vice versa. The PWN must explain why, what alternatives were considered, and what data supports this decision.

The school is refusing your request

You asked for additional services, a specific accommodation, or an evaluation in a new area — and the school said no. The PWN explains their reasoning and the data they relied on. This is actually useful: it creates a paper record of the school’s position that you can challenge.

The school wants to end a service

Your child has been receiving speech therapy three times a week, and the school proposes to reduce it. You get a PWN before that change takes effect.

The school found your child ineligible

After an evaluation, the team determined your child does not qualify for special education services. The PWN explains the basis for this finding.

What a PWN Is NOT

A PWN is not a final decision that you must accept. It is notice — it informs you of what the school intends to do or has decided. You have the right to disagree and the right to pursue your options.

A verbal conversation is not a PWN. A phone call is not a PWN. An email — even from the principal — is not a PWN. If the school communicates a significant decision verbally, you can and should request it in writing.

What to Do When You Receive a PWN

Step 1: Read it carefully — all of it

Don’t skim. Read every line. Note what the school says it’s proposing, what reasoning it gives, and what evidence it cites.

Step 2: Check whether it’s complete

Does it include all seven required elements listed above? If not, it’s deficient. Write a short letter noting the missing elements and requesting a compliant PWN: “I have received the Prior Written Notice dated [date]. It appears to be missing [specific elements]. Please provide a complete PWN in compliance with 34 CFR 300.503.”

Step 3: Decide whether you agree, disagree, or need more information

You have three options:
– Agree: The school’s proposal makes sense and you support it.
– Disagree: You believe the proposal is wrong, inadequate, or harmful to your child.
– Need more information: The reasoning isn’t clear or you want to understand the evidence better.

Step 4: If you disagree, respond in writing within a reasonable timeframe

There is no strict deadline to respond to a PWN (unlike some other IDEA timelines), but responding promptly preserves your options. A written response that clearly states your disagreement and the basis for it is the foundation of any dispute.

Your response might say: “I am writing to express my disagreement with the Prior Written Notice dated [date]. I do not consent to [proposed action] for the following reasons: [your reasons]. I am requesting an IEP meeting to discuss this further.”

Step 5: Know your escalation options

If you and the school cannot reach agreement, you have several options:
– Request mediation (free, voluntary, confidential)
– File a state complaint (free, 60-day investigation timeline)
– Request a due process hearing (formal legal proceeding)

You can pursue mediation and file a state complaint simultaneously. A state complaint is often the most efficient first step when the school has clearly violated a procedural requirement.

When the School Doesn’t Provide a PWN

If the school makes a significant change without providing you a PWN — changing placement, reducing services, denying a requested evaluation — that is a procedural violation of IDEA.

Document the change and when you learned about it. Then write to the school district: “I was not provided with a Prior Written Notice before [specific change] was made. I am requesting an immediate written explanation and ask that this violation be remediated promptly.”

This kind of procedural violation can be the basis of a state complaint.

PWN in Canada

Canada does not have a formal Prior Written Notice requirement equivalent to IDEA. However, provincial Education Acts generally require schools to notify parents before making changes to a student’s educational program, and to provide written documentation of placement decisions.

In Ontario, the IPRC process involves formal written notice of identification and placement decisions. Parents who disagree have 30 days from the written decision to appeal to the Special Education Appeal Board (SEAB).

In other provinces, the notice and appeal mechanisms vary — consult your provincial Education Act or contact your provincial parent resource centre.

Turning a PWN Into Action

A PWN is a starting point, not an ending point. When you receive one, IEP Navigator’s Dispute and Appeal Letter tool can help you draft a formal, legally-grounded response that cites the relevant IDEA provisions and makes your position clear.
