The document discusses tables of specification, which are charts that provide a graphic representation of the content and educational objectives of a course or curriculum. Tables of specification break content into topics and objectives and assign a number of test items or points to each. They help ensure tests are balanced and validly measure the most important objectives and content areas. Teachers can use tables of specification as a planning guide to structure lessons and assignments and ensure all content areas are adequately covered. They benefit students by promoting balanced assessments and building confidence in a test's fairness.
