As long as a student qualifies for special education, the IEP is mandated to be regularly maintained and updated up to the point of high school graduation or prior to the 21st or 22nd birthday. If a student in special education attends university upon graduation, they are no longer "children with disabilities" under the Individuals with Disabilities Education Improvement Act of 2004 and are instead protected under Section 504. They can apply for and receive Section 504 accommodations, but the process is very different. Placements in public schools often occur in "general education" classrooms. Other types of placements include RSP (within a resource room), Special Day Class, Self Contained Class, Co-Teacher and specialized classes, or sub-specialties taught by a special education teacher. Students can also be removed from an IEP if it is determined the student is no longer eligible upon reevaluation.
