The transition from school to adulthood is a pivotal time in the lives of all students. For a student with Autism Spectrum Disorder (ASD), change of any kind can be challenging, and a transition as momentous as this can seem especially daunting. Thoughtful planning, sound information, and open communication will help parents support young adults and their transition team to create a solid transition plan that leads to success. It is the goal of this guide to support families with this process. This guide is written for parents and guardians of autistic individuals who are preparing to transition into adulthood. This guide is divided into seven chapters: (1) Agency Help/Legal Information; (2) Transition Plan; (3) Student-Centered Transition Planning; (4) Vocation and Employment; (5) Postsecondary Education; (6) Life Skills; and (7) Looking Ahead.
