A written notice the school must give you before they propose — or refuse — to change anything about your child's evaluation, eligibility, placement, or services.
Prior Written Notice (often called PWN) is a document the school district is required to give you any time they want to change something about your child's special education — or refuse to change something you've asked for.
This includes proposals or refusals about:
The PWN must be in writing, in language you can understand, and provided to you before the change takes effect. Federal law (34 CFR §300.503) makes this a parent right — it's not optional for the district.
The PWN requirement comes from 34 CFR §300.503, implementing the Individuals with Disabilities Education Act (IDEA). State special education regulations sometimes add to this baseline but cannot reduce it. The Office of Special Education Programs (OSEP) has issued multiple Dear Colleague letters reinforcing that PWN is a substantive right and that procedural violations can rise to the level of a denial of FAPE when they significantly impede the parent's opportunity to participate.
Not all PWN failures rise to a denial of FAPE — but persistent or significant procedural violations can.
Federal regulations list seven required elements. A PWN that's missing any of these is procedurally defective:
1. A description of the action the district proposes or refuses 2. An explanation of why the district is proposing or refusing that action 3. A description of each evaluation, test, record, or report the district used to make the decision 4. A description of any other options the IEP team considered and the reasons they were rejected 5. A description of any other factors relevant to the proposal or refusal 6. A statement that the parents have procedural safeguards (and how to obtain a copy) 7. Sources parents can contact to help them understand the safeguards
If you receive a PWN that says only 'we will increase reading services to 60 minutes per week' with no other detail, it does not meet the federal standard.
Any time the district proposes OR refuses to:
A refusal counts. If you asked for an FBA and the district said no, you are entitled to a PWN explaining the refusal. If you asked for extended school year services and the team declined, you are entitled to a PWN.
A PWN is also required when the district proposes a change — not just when they refuse one.
If the district refused something verbally or hasn't followed up in writing, you can request a PWN in writing. Email is fine (it creates a paper trail). A simple request might be:
'On [date], during our IEP meeting, the team declined my request for [specific request]. Please provide me with the Prior Written Notice for this decision as required by 34 CFR §300.503, including the seven required content elements.'
Keep your email. If they don't respond, or the PWN they send is inadequate, that itself can become evidence in a state complaint or due process complaint.
Understanding the topic is one thing; using it in a meeting is another. SENTINEL·IEP gives you plain-language reference and a companion that follows the conversation in real time — so you can recognize this when it comes up and know what to ask.
