Prior Written Notice (PWN) Explained — Pennsylvania

What Is Prior Written Notice in an IEP? A Pennsylvania Parent's Guide

If your child receives special education services in Pennsylvania, one of the most powerful — and most overlooked — documents in the process is the prior written notice (PWN). Understanding what it is, when you're entitled to receive it, and how to ask for it can make a real difference in getting your child the support they need.

What Prior Written Notice (PWN) Actually Means

Prior written notice is a formal written statement that your child's school district must give you before it takes — or refuses to take — any significant action related to your child's identification, evaluation, educational placement, or the provision of a free appropriate public education (FAPE) (20 U.S.C. § 1401(9); 34 C.F.R. § 300.17).

Think of it as the district's documented explanation of its decisions. Any time the school proposes to change something meaningful about your child's program — or says "no" to something you've requested — a PWN is required.

The Federal Law Behind PWN

Prior written notice is grounded in the Individuals with Disabilities Education Act (IDEA). Specifically, 20 U.S.C. § 1415(b)(3) and (c)(1), along with 34 C.F.R. § 300.503, spell out exactly what the notice must include:

• A description of the action the district is proposing or refusing
• An explanation of why the district is proposing or refusing that action
• A description of each evaluation, assessment, record, or report the district used in making its decision
• A statement of your procedural safeguards — your rights as a parent — and how you can get a copy
• Other options the district considered and why those were rejected
• Other factors relevant to the decision

Plain language matters here. Under federal regulations, the PWN must be written in language that is understandable to the general public and provided in your native language when possible (34 C.F.R. § 300.503(c)).

When Must Pennsylvania Schools Provide a PWN?

In Pennsylvania, the requirement to provide prior written notice applies across the entire special education process. Here are the most common situations when you should expect to receive one:

• Before or after an initial evaluation — When the district proposes to evaluate your child for the first time (or refuses to evaluate), a PWN must accompany or precede that action. Note that under Pennsylvania regulations, the district must complete an initial evaluation within 60 calendar days of your consent (22 Pa. Code § 14.123(b)).
• Before any change to your child's IEP — Whether the school wants to add a service, remove a service, change placement, or change goals, a PWN must be issued.
• When the school refuses a parent request — If you ask for an evaluation, a new service, a placement change, or any other action and the district says no, they must provide a PWN explaining why.
• Before the initial IEP is developed — Once an evaluation is complete, Pennsylvania requires the district to develop an IEP within 30 calendar days (22 Pa. Code § 14.131). A PWN should accompany the proposed IEP.
• Before a re-evaluation — Any time the team proposes or refuses to re-evaluate your child.

Key point for Pennsylvania families: Verbal conversations at an IEP meeting are important, but they are not a substitute for prior written notice. If a decision is made or a request is denied, you have the right to see it documented.

How to Request a Prior Written Notice in Pennsylvania

You don't have to wait for the district to hand you a PWN unprompted — you can ask for one directly. Here's how to do it confidently and constructively:

Step 1: Put Your Request in Writing

Send an email or letter to your child's special education director or case manager. Written requests create a clear paper trail. A simple message might read:

"I am writing to formally request a prior written notice regarding [describe the action or refusal]. Please provide the required PWN, including the reasons for this decision and any evaluations or records that were considered."

Step 2: Reference the Applicable Law

Mentioning the relevant regulation shows you understand the process and helps move things along. You can note that your request is made pursuant to 20 U.S.C. § 1415(b)(3) and 34 C.F.R. § 300.503.

Step 3: Keep Copies of Everything

Save all emails and letters. If the district provides a PWN, review it carefully. Make sure it actually addresses each of the required elements listed above — especially the explanation of why the action was proposed or refused, and what other options were considered.

Step 4: Follow Up if You Don't Receive One

If a reasonable amount of time has passed (typically 5–10 school days) and you still haven't received a PWN, follow up in writing and note the date of your original request.

What to Do If the PWN Is Missing or Incomplete

A missing or vague prior written notice is not a dead end — it's a starting point for a productive conversation.

• Request clarification in writing. Ask the district to revise or expand the notice to address the required elements.
• Contact the Pennsylvania Training and Technical Assistance Network (PaTTAN), which provides free parent support resources throughout the state.
• Reach out to the Pennsylvania Office for Dispute Resolution (ODR), which offers mediation and facilitated IEP meetings — low-stakes, free options for resolving disagreements.
• Consult a special education advocate or attorney if the missing PWN relates to a high-stakes decision, such as a change in placement, a disciplinary action, or a denial of an evaluation. These situations benefit from professional guidance.

Why PWN Matters: Your Child's Paper Trail

Prior written notice is one of the most important procedural safeguards in IDEA because it creates accountability and transparency. Every PWN you receive becomes part of your child's permanent record and can be critically important if a disagreement ever escalates to mediation or a due process hearing.

More practically, the process of issuing a PWN requires the district to slow down and formally articulate its reasoning. That discipline — having to write down why — often leads to more thoughtful decisions that genuinely serve your child.

You deserve to know what is being decided about your child's education, why it is being decided, and what alternatives were considered. Prior written notice is the mechanism that makes that possible.
