This document discusses and compares progressive tests and achievement tests. It defines progressive tests as informal tests used to measure student growth over time, with examples being year-to-year or semester-to-semester tests. Achievement tests are more formal tests taken at a single point in time to measure performance against a level, with examples being final exams or public exams. The document outlines several key differences between the two types of tests, such as progressive tests focusing on individual students and growth over time, while achievement tests provide general judgments of successes and level students. Both can motivate students, but progressive tests involve teachers more while institutions play a larger role in achievement tests.
