Quizplus · Accepted Answer

Test-retest reliability and validity are two separate concepts. Test-retest reliability refers to the consistency of scores when the same test is administered to the same group of people at two different points in time. Validity refers to the extent to which a test measures what it claims to measure. While high test-retest reliability is important for a test to be considered reliable, it is not a necessary condition for validity. A test can have high validity but low test-retest reliability if the construct being measured is inherently unstable or changes over time.
