c.Predictive validity- degree of accuracy of how a test predicts the levels of performance in acertain activity which it intends to foretell.
d.Construct validity- refers to the agreement of test results with certain characteristics whichthe test aims to portray.
2. RELIABILITY- degree of consistency of measurement that it gives.Factors of reliability:
a. Adequacy- the appropriate length of the testb. Objectivity- a test is objective if it yields the same score no matter who checks it or even if itis checked at diff. times.
