validity, a test of a construct is correlated with other tests designed to measure theoretically similar constructs. For instance, to assess the convergent validity of a test of mathematics skills, the scores on the test are correlated with scores on other tests that are also designed to measure basic mathematics ability. High correlations between the test scores would be evidence of convergent validity.

Convergent evidence is best interpreted in conjunction with discriminant evidence. That is, patterns of intercorrelations between two
