After more than two decades of federal transition legislation, students with disabilities continue to have significantly poorer postschool outcomes as compared to their peers without disabilities. One reason for these outcomes is that educators are inadequately prepared to provide the services required under the Individuals with Disabilities Education Act (IDEA). This brief provides an overview of critical issues related to transition professional development and highlights current models of improving results for youth by supporting practitioners with in-service and pre-service training. A brief list of resources is also included.
