There are generally two types of achievement tests, norm-referenced and criterion-referenced tests. Most achievement tests are norm-referenced. The individual's responses are scored according to standardized protocols and the results can be compared to the results of a norming group. Norm-referenced tests can be used to underline individual differences, that is to say, to compare each test-taker to every other test-taker. By contrast, the purpose of criterion referenced achievement tests is ascertain whether the test-taker mastered a predetermined body of knowledge rather than to compare the test-taker to everyone else who took the test. These types of tests are often a component of a mastery-based classroom.
