by Robert Kornfeld and Kalman Rupp

This article summarizes the results of a major social experiment initiated by the Social Security Administration to test case management as a tool of promoting employment among persons with moderate to severe disabilities. This comprehensive analysis shows the benefits of using an experimental design to derive realistic net outcome estimates. While the results cannot be generalized to other case management interventions, they are nevertheless instructive for planning new initiatives.

The Development of the Project NetWork Administrative Records Database for Policy Evaluation

This article describes the development of SSA's administrative records database for the Project NetWork return-to-work experiment targeting persons with disabilities. The article is part of a series of papers on the evaluation of the Project NetWork demonstration. In addition to 8,248 Project NetWork participants randomly assigned to receive case management services and a control group, the simulation identified 138,613 eligible nonparticipants in the demonstration areas. The output data files contain detailed monthly information on Supplemental Security Income (SSI) and Disability Insurance (DI) benefits, annual earnings, and a set of demographic and diagnostic variables. The data allow for the measurement of net outcomes and the analysis of factors affecting participation. The results suggest that it is feasible to simulate complex eligibility rules using administrative records, and create a clean and edited data file for a comprehensive and credible evaluation. The study shows that it is feasible to use administrative records data for selecting control or comparison groups in future demonstration evaluations.
