Quizplus · Accepted Answer

Administering two instruments within a short period of time is necessary to establish alternate forms reliability, which measures the extent to which two versions of the same test or two different tests constructed to assess the same construct produce similar results. Other types of reliability include interrater reliability, which measures the extent to which different raters or judges agree in their ratings, and test-retest reliability, which measures the stability of a test score over time. Predictive validity and content validity are types of validity, which refer to the extent to which a test measures what it is supposed to measure.
