Comprehensive Achievement Monitoring (CAM) is a system designed to provide a curriculum defined in terms of performance objectives, test items to measure student performance on each objective, a set of comparable test forms to evaluate performance, testing throughout the period of the course, computerized analysis and reporting of results after test administration, interpretation of results by teachers and students leading to decisions on curriculum and study priorities, and modification of curriculum, instructional activities, and CAM. This report overviews the CAM philosophy, and then describes a practical application of CAM in beginning algebra at Carlmont High School, the CAM basic reading skills program at Menlo-Atherton High School, the application of CAM for English at Notre Dame High School, and CAM and teacher decision-making for the team Geography program at Sequoia High School.
