1.1. Does the test measure the instructional objectives
2. Criterion-Related Validity
2.1. Concurrent validity provides a good method of estimating the validity of a new test.
2.2. Predictive validity refers to how well the test predicts some future behavior of the examinee.
3. Construct Validity
3.1. Is determined by finding whether test results corresponds with scores on other variables as predicted by a theory.
4. Split Half Reliability
4.1. Even estimates divide a test into halves and correlate the halves with one another because these correlations are based on half test, the obtained correlation underestimate the reliability of the whole test.
5. Test- retest Reliability
5.1. Obtained by administrating the same test twice to the same group of individuals with the same time interval between testing and correlating the scores.
6. Alternate-forms Reliability
6.1. Obtained by administrating tow alternate or equivalent forms of a test to the same group and correlating their score.
