Abstract This chapter examines the transition of autistic individuals into adulthood, beginning with the concept of emerging adulthood, a developmental stage characterized by increasing autonomy and identity formation. It explores how evolving conceptions of autism—from deficit- based to identity-oriented perspectives—shape the experiences of autistic adults, whose growing population intensifies the demand for supportive services. The chapter highlights the educational, employment, and independent living challenges faced by young autistic adults, emphasizing the “services cliff” that restricts access to transitional support. It also analyzes co-occurring mental health conditions, process impairments such as executive dysfunction and self-regulation, and the importance of recognizing autistic individuals’ strengths, self-determination, and self-knowledge in fostering autonomy. Finally, the chapter introduces the Stepped Transition to Employment and Postsecondary Education Success (STEPS) Program, outlining its evidence-based framework, theoretical foundations, and proven effectiveness in enhancing transition readiness, independence, and overall well-being among autistic young adults.
