Conceptual Issues in Developing Return on Investment Estimates of Vocational Rehabilitation Programs

We provide an overview of the basic conceptual issues involved in estimating the return on investment (ROI) of state vocational rehabilitation (VR) programs.

Finally, we discuss different ways of implementing ROI calculations and suggest that rate of return type analysis is appealing for VR evaluations where there is no widely accepted discount rate
