2. B. Predictive - determined by correlating test scores with measure. Is collected over a period of time.

3. A. Concurrent Criterion-Related Validity Evidence- determined by correlating test scores with measure. Scores and measure must be taken at the same time.

4. 1. Content - Questions are inspected to insure correlation with what is supposed to be covered by test. (Kubiszyn & Borich, page 336)

5. 3.Construct - relationship with information corresponds with a theory. (Kubiszyn & Borich, page 329)

6. 2. Criterion- Test scores are correlated with external criterion. The two types of criterion are concurrent criterion-related validity and predictive.

7. Validity--Test measures what it is supposed to measure.

11. 3. Internal Consistency- Test measure a single unit or trait.

12. 2. Alternate Forms or Equivalence- Two forms of a test are given to the students and the scores are correlated. Short time period between both tests.

13. 1. Test-Retest on Stability- Test is given twice. Correlation between the two sets of scores is determined. (Kubiszyn & Borich, page 338)

14. Reliability-- Test gives the same or similar score consistently.
