When parents attend an Individualized Education Program (IEP) meeting, it’s easy to focus on the discussion and overlook one of the most powerful documents in the special education process: Prior Written Notice (PWN). Many families don’t realize this document can become one of their strongest advocacy tools when disagreements arise or important decisions are made. Under the Individuals with Disabilities Education Act (IDEA), schools must provide Prior Written Notice whenever they propose or refuse certain actions involving a child’s special education services. Understanding how to use this requirement strategically can help parents protect their child’s educational rights while creating a clear paper trail for future decisions.
