The Discrepancy Evaluation Model

Part of the Evaluation in Education and Human Services book series (EEHS, volume 6)


The word evaluation is used loosely to encompass many different activities and purposes. When educators evaluate a reading program, they may be referring to deciding which of several reading programs their school district should adopt; when evaluating a school-bell schedule, they may mean finding out how popular the schedule is among students and faculty and what the advantages and disadvantages of several other bell schedules may be; when evaluating students, they may mean administering achievement or psychological tests; and so on.

    The DEM was first put forth by Malcolm Provus; see Discrepancy Evaluation, McCutchan, 1971. It was further developed at the Evaluation Research Center in 1971–1975 by a team of people, including the author, led by Malcolm Provus. Different versions of the DEM have arisen. The views presented here are those of the author.Google Scholar

    This does not necessarily mean that the DEM evaluator will not be open to unexpected events. How to handle this problem is negotiated between client and evaluator; the important thing, again, is for the evaluator to stay away from setting and deciding on his/her own what information to collect.Google Scholar
