What is a Prior Written Notice (PWN)

Prior Written Notice (PWN) is a required written explanation that a school must provide when it proposes or refuses to initiate or change:

• Identification

• Evaluation

• Educational placement

• The provision of Free Appropriate Public Education (FAPE)

Under the Individuals with Disabilities Education Act (IDEA), this requirement is set forth in (34 C.F.R. § 300.503).

| What a PWN must include

PWN provide a clear, detailed explanation of the decision, including:

•  A description of the action proposed or refused

• An explanation of why the agency is taking or refusing the action

• The data, evaluations, records, or reports used as the basis for the decision

• Other options considered and the reasons those options were rejected

• Other relevant factors considered by the agency

• A statement that parents have procedural safeguards and how to obtain them

• Sources for assistance in understanding these provisions

(34 C.F.R. § 300.503(b))

A vague or incomplete notice does not meet legal requirements.

| Why This Right Matters

Prior Written Notice is one of the most important procedural safeguards available to parents. It creates a clear, written record of the district’s decisions, including the reasoning and data relied upon.

PWN allows parents to:

• Fully understand what the district is proposing or refusing

• Evaluate whether decisions are supported by appropriate data

• Identify gaps, inconsistencies, or unsupported conclusions

• Preserve a clear record for future meetings, complaints, or dispute resolution

Without complete and accurate PWN, parents may be unable to participate meaningfully in decision-making.

| Legal Significance

Failure to provide adequate PWN may constitute a procedural violation and may rise to the level of a denial of a Free Appropriate Public Education (FAPE) if it:

• Impedes meaningful parental participation

• Results in a loss of educational opportunity

(34 C.F.R. § 300.513(a)(2))

How to Request PWN

When a request is denied, parents may request that the refusal be documented through Prior Written Notice.

A simple request may include:

“Please provide Prior Written Notice for the district’s refusal, including the data and rationale supporting this decision, in accordance with 34 C.F.R. § 300.503.”

PWN should be requested when:

• A service or support is denied

• An evaluation is refused

• A proposed change is not implemented

• A decision is made without clear explanation or supporting data

Important Clarification

A public agency may not rely on informal communication (verbal statements, emails, or meeting discussions) in place of required written notice.

If a refusal is communicated informally, parents may request that it be formally documented through PWN.




Enforcement Standard

Failure to provide Prior Written Notice may:

• Reduce transparency and accountability

• Impede meaningful parent participation

(34 C.F.R. § 300.513(a)(2))

• Affect the integrity of the decision-making process

Core Principle

When a request is refused, the district must either document and justify the decision in writing through Prior Written Notice—or correct the decision.
