What defines an objective written test effectively?

An effective objective written test is characterized primarily by its ability to measure what it is intended to measure accurately. This means that the test is structured in a way that aligns with the learning objectives and outcomes, ensuring that it assesses the specific knowledge or skills that have been taught. An objective test typically features clear, unambiguous questions with a specific set of answers, allowing for consistent scoring.

This type of test provides a standardized method for evaluating student performance, eliminating variations in grading that might occur in more subjective assessments. Consequently, the focus on clear and measurable outcomes is fundamental to the integrity of the testing process, making option B the most pertinent answer in this context. The measure of validity, or how well the test reflects the content it aims to assess, is a crucial aspect of an effective objective written test.
