• Predictive Validity –how well predictions made from the test are confirmed by evidence gathered at some subsequent time.
• Test-retest Reliability –achieved by administering an instrument twice to same group of participants and then computing the consistency of the scores.
• Equivalent Forms Reliability –measured by administering two tests identical in all aspects except the actual wording of items.
