The extent to which the stimulus materials or situations composing the test call for a range of responses that represent the entire domain of skills, understandings, or behaviors that the test is intended to measure.
A characteristic possessed by an assessment instrument whose contents accurately reflect actual job requirements. For example, a typing test would likely be a highly content-valid instrument for assessing a person's qualifications to be a clerk-typist. Also referred to as "face validity."
The content validity of a test is estimated through a logical process in which subject matter experts (SMEs) review the test items in terms of their match to the content areas specified in the test blueprint. For certification and licensure tests, this is typically the most important type of validity.
Content validity indicates the extent to which the content of the test samples the subject matter or situation about which conclusions are to be drawn. Methods used in determining content validity are textbook analysis, description of the universe of items, adequacy of the sample, representativeness of the test content, inter-correlations of subtest scores, and opinions of a jury of experts.
The extent to which the content of an examination contains a balanced and adequate sample of questions representative of the knowledge and skills an individual needs for successful and competent job performance.
In psychometrics, content validity (also known as logical validity) refers to the extent to which a measure represents all facets of a given social concept. For example, a depression scale may lack content validity if it only assesses the affective dimension of depression but fails to take into account the behavioral dimension.
