Quality Control (QC) regulations for the following federal entitlement programs are discussed: Aid to Families with Dependent Children (AFDC), Medicaid, Supplemental Security Income Program, and Food Stamp Program. Implications of these QC procedures and for the Department of Education's approach to QC regulations are also considered. Each set of regulations dealing with QC in the program is described according to several characteristics, including programmatic relationships among the federal, state, and local governments; QC responsibilities and procedures; standards and measures; frequency of reporting; and incentives. It is concluded that the structure of the delivery system is a critical factor in determining the regulatory approach to QC taken by federal agencies. Results of the review include: the regulations mandate the inclusion of not only computation and reporting of error rates, but also the development and implementation of corrective action plans; standards, measures, and frequency of computing and reporting measures are fairly consistent across programs; most regulations identify both positive and negative incentives; and the character of the regulations differ across agencies.
