The Discrepancy Evaluation Model (DEM), developed in 1966 by Malcolm Provus, provides information for program assessment and program improvement. Under the DEM, evaluation is defined as the comparison of an actual performance to a desired standard. The DEM embodies five stages of evaluation based upon a program's natural development: program design, installation, process, product, and cost benefit analysis. The evaluation information collected by the DEM facilitates rational decision making by career planning and placement counselors. These decisions can be divided into three classes: decisions related to program design or analysis, decisions concerning the achievement of both intermediate and final goals, and decisions about the program in operation. As an example, the DEM is applied to a university career planning program. This particular program assists students in determining their interests and goals, implementing career and postgraduate decisions. (Author/MV)
