1. Reliability
1.1. Test-retest
1.1.1. A test is administered two times within very short time frame to the same group of students and the results of both tests are compared
1.2. Alternate Forms
1.2.1. Tests with the same equivalency are administered to the same group of students and the results are correlated.
1.3. Internal consistency estimates of reliability
1.3.1. Split-half methods
1.3.1.1. The dividing of a test into equal halves and mathematically comparing the two.
1.3.2. Kuder-Richardson methods
1.3.2.1. Comparison of the commonality of test items to a test of equal value.
2. Validity
2.1. Criterion-Related Validity Evidence
2.1.1. Concurrent Criterion-related evidence
2.1.1.1. A way of determining the validity of a new test to an older test and comparing the two
2.1.2. Predictive validity evidence
2.1.2.1. Results of test and future outcomes are correlated. (Can this test predict the future performance of an individual?)
2.2. Construct Validity Evidence
2.2.1. Are the outcomes of the test relevant to instruction?
2.3. Content Validity Edvidence
2.3.1. Do the test items match up with the objectives?
