The New York State Education Department's state-wide testing program using the Pupil Evaluation Program (PEP) is shown to be generally inadequate for judging program or school effectiveness, or for making decisions which would allow improvements in program effectiveness. The Comprehensive Achievement Monitoring (CAM) system can, however, be adapted to meet the information needs at different levels. Several experimental programs in which CAM models have been developed and implemented are described. Included are the use of CAM in research and development, demonstration projects in which CAM is utilized for course revision in convention classroom instruction, CAM combinations with other evaluative techniques for the purpose of evaluation of the work of individual students, and the use of CAM and small computers to evaluate student progress and assign students to instructional treatments. Finally, the support activities of the State Education Department to local school districts in the areas of program evaluation and management of the instructional process are outlined. (DG)
