Research recognizes the power of assessment to amplify learning and skill acquisition. Assessing students is a fundamental ingredient of effective teaching. It is the tool that enables teachers to measure the extent to which a student or group of students have mastered the material taught in a lesson or a class or during the school year, and it gives instructors the necessary information to modify instruction when progress falters. Assessment affects decisions about grades, placement, advancement, instructional strategies, curriculum, special education placement, and funding. It works to improve instruction in the following ways: (1) as a diagnostic tool, (2) by providing feedback on progress measured against benchmarks, (3) as a motivating factor, and (4) as an accountability instrument for improving systems.
