This occurs when items on the test represent the entire range of possible items the test should cover.
This occurs when the test has demonstrated its effectiveness in predicting criterion or or indicators of a construct.
When the criterion measures are obtained at the same time as the test scores Concurrent Validity occurs.
This happens when the criterion measures are obtained at the time after the test.
When a test demonstrates association between test scores and the prediction of a theoretical trait, Construct Validity occurs.
This type of reliablity is used when the same test is used, but different people are taking it.
This method is used when the same people take the test, but at different times.
When different people take different test at the same time, this occurs.
Different questions, but the same construct is used here.
