The extent to which the same score could be expected from a candidate taking the same test on different occasions is known as what?

• A. Reliability
• B. Validity
• C. Distractor
• D. Denotation

Answer: (A)

Reliability is about consistency of measurement. When the same test is taken by the same person on different occasions, a reliable test will yield similar scores if the person’s ability hasn’t changed and the testing conditions are reasonably similar. This idea of stable, repeatable results across time is often called test-retest reliability. High reliability means the score reflects true ability rather than random error or day-to-day fluctuations. By contrast, validity is about whether the test measures what it’s supposed to measure, not about consistency over time. The other terms describe parts of test design or language, not the stability of scores.
