In one week, the outdated Building the Legacy: IDEA 2004 (Legacy) website will automatically redirect users to the new Individuals with Disabilities Education Act website (new IDEA website).
So, set those bookmarks to https://sites.ed.gov/idea/
While the Legacy site will redirect users to the new IDEA website on April 30, content from the Legacy site is available for reference on the new IDEA website’s “Building the Legacy: IDEA 2004” historical reference page.
