Types of validity testing
Face validity - Extent to which the content of the test measures all of the knowledge is included to be tested, according to the test takers
Content validity - Extent to which the content of the test measures all of the knowledge is included to be tested, according to expert judges
Criterion related validity - Measure of the extent to which a test’s results correlate with other accepted measures of what is being tested
Predictive validity - Extent to which the test accurately forecasts a specific future result
Construct validity - Extent to which the test actually measures the hypothetical construct or behavior it is designed to assess. [Considered the true measure of validity]
Performance tests
Test taker knows what he or she should do in response to questions or tasks on the test, and it is assumed that the test taker will do the best he or she can to succeed.
Eg: SATs, AP tests, Wechsler intelligence tests, Stanford-Binet intelligence tests, and most classroom tests
Observational tests
Person being tested does not have a single, well-defined task to perform, but rather is assessed on typical behavior or performance in a specific context.
Eg: Interviews
Self-report tests
Require the test taker to describe his or her feelings, attitudes, beliefs, values, opinions, physical state, or mental state on surveys, questionnaires, or polls.
Eg: MMPI
