Validity and Reliability

1. internal consistency

1.1. internal consistency is measure one skills and if the students get the item right them they will get a similar one.

1.1.1. split -half and Kuder-Richardson is to methods use to estimate the internal testing.

2. alternate Forms

2.1. is test a group of children at a different time of day.

3. test -rest or stability

3.1. is testing group and then testing again and comparing scores. if the group is tested on reading then they have to to be retested to determine the correlation between the scores.

4. construction

4.1. is finding testing results correspond with scores on other variables as predicted by some rationale or theory.

5. criterion

5.1. is establishing scores from tests are correlated with an external criterion.

5.1.1. concurrent is measures that can be administered at the same time.

6. content

6.1. is assessing is what skill you want to cover on the test.
