Efficacy of a School-Based Comprehensive Intervention Program for Adolescents with Autism

We tested the efficacy of a comprehensive intervention program designed for high school students across the autism spectrum, the Center on Secondary Education for Students with Autism (CSESA) model, in a cluster randomized control trial involving 60 high schools in three states (California, North Carolina, Wisconsin), with implementation occurring over a 2-year period. We examined outcomes for the schools, students (N = 547), and families. At the conclusion of the study, CSESA schools had significantly higher program quality than the services-as-usual (SAU) schools. In addition, students in the CSESA schools had significantly higher total attainment of educational goals than students in SAU schools. There were not significant differences between the two groups on standardized assessment outcomes. We discuss implications for intervention implementation and future research with this population in the public school context.
