The correlation between test scores and criterion scores is a measure of validity. It indicates the extent to which the test measures what it is supposed to measure (i.e. the criterion). Reliability is a separate concept that refers to the consistency of test scores over time or across different test versions. Content validity is the degree to which the test items adequately cover the content domain of interest.
