Statistically measured correspondence between judgments by observers of a common event.Ī measure of the internal consistency of a measure, calculated by dividing the total set of test items into halves and determining the correlation between the two subsets of items. The interrelatedness of items on a test, demonstrating that they are measuring the same construct. The degree to which a test score predicts future behavior or performance on an accepted criterion measure.Ĭonsistency and correlation of test scores across test replications. The degree to which a test assesses the specific constructs it is intended to assess, based on the theorized relationships between the construct of interest, other constructs, and observable indicators. The extent to which test scores or responses demonstrate a strong relationship with scores or responses on conceptually similar tests.Įvaluating the validity of a measure based on its relationship to a specific criterion.Ī form of construct validity that defines how well the test or measure does not correlate with unrelated constructs. The extent to which a test reflects the various components of the construct it is intended to measure. The extent to which a measure accurately assesses the construct or latent attribute that it is intended to measure. The extent to which the results of a test or measurement correspond to those of a previously established and related measure, collected at the same point in time.

The extent to which evidence and theory support specific interpretations of test scores for the proposed use of the test.
