This study reports the results of a multi-site, parallel block randomized clinical trial to expand the previous findings regarding the implementation of Project SEARCH plus ASD Supports (PS + ASD) on employment outcomes upon graduation from high school. Participants were 156 individuals with significant impact from ASD between the ages of 18-21. There was a significant difference between treatment and control groups with 73.4% of the treatment group acquiring competitive employment at or above minimum wage by 1-year after graduation compared to 17% of the control group for whom data was provided. At 1-year, employed treatment group participants worked an average of 21.2 h per week (SD = 9) for a mean hourly wage of $9.61 per hour (SD = $1.55).
