Which term describes the degree to which scores from a particular test are consistent over repeated administrations?

The term that describes the degree to which scores from a particular test are consistent over repeated administrations is reliability. Reliability refers to the consistency of measurement across different occasions or tests. When a test is reliable, it suggests that if the same test is administered multiple times under comparable conditions, the results will be similar or the same. This consistency is critical in research and assessment contexts because it implies that the test is measuring the intended construct rather than varying significantly due to external factors.

Validity, on the other hand, refers to the extent to which a test measures what it claims to measure. Consistency, while an important concept, is not a specific term used in psychometrics to define measurement quality. Stability can relate to reliability, particularly concerning how scores maintain their accuracy over time, but reliability encompasses both the elements of consistency and stability in test scores. Thus, reliability is the most comprehensive and accurate term for this concept.
