The 1990 reauthorization of the Individuals with Disabilities Education Act (IDEA) brought several significant changes. It officially changed the name of the legislation to IDEA and recognized autism and traumatic brain injury as separate categories of disability. This reauthorization also mandated the inclusion of an individualized transition plan (ITP) for students by age 16 to facilitate their transition from school to post-school activities. Additionally, it repealed the immunity that states previously had from lawsuits for violations of IDEA, thus increasing accountability.
