Which is not a characteristic of a good test?

A good test is designed to provide accurate and fair measurements of student knowledge or skills. Therefore, characteristics that ensure fairness and accuracy are highly valued. Bias is explicitly not a characteristic of a good test; rather, it is a flaw that test developers strive to eliminate. A biased test unfairly favors or disadvantages certain groups of test-takers due to factors unrelated to the construct being measured, leading to inaccurate and inequitable results.

• A: Reliability is a crucial characteristic, meaning a good test consistently produces similar results under similar conditions.
• B: Validity is another essential trait, indicating that the test accurately measures what it is intended to measure.
• D: Objectivity refers to the test's ability to be scored and interpreted without personal opinions or biases influencing the results, ensuring fairness.
