It is a test blue print. It is a matrix. It is a tool used to ensure that a test measures the content and thinking skills that the test ensures to measure.
Ensures that the fair and representative questions appear on the test. Improves the quality of teacher’s evaluations based on the tests constructed. Helps teachers identify the type of items they need to include on their tests.
Provides the teacher with the evidence that a test has content validity, that it covers what should be covered. Helps measure higher thinking skills and lower thinking skills of students.
Content Outline – lists of topics and important objectives/learning outcomes under the topic. Categories – serves as a reminder or a check on the cognitive complexity of the test. Number of items – serves as a check as to the number of items for each objective or content topic listed.
