This chapter presents results from the most comprehensive and expansive application of the structural VR-Return on Investment (VR-ROI) model to date, which leverages longitudinal quarterly employment and earnings data to assess the impact of VR across eight distinct state agencies, four distinct disability groups, and seven to nine distinct VR services. For the first time, the VR-ROI model is employed to concurrently compare short- and long-run labor market outcomes across a broad spectrum of agencies and disability groups, which yields unparalleled insights into the diverse effects of vocational rehabilitation services. This analysis sets the stage for comprehensive understanding of VR’s efficacy and provides a detailed picture that informs stakeholders about the nuanced benefits and challenges within these critical programs.
