Validity

Predictive Criteria

validity evidence yields numerical indices of validity

Must revisit the learner after a period of time to see if the predictions were valid

Predicts future behavior

Subtopic

Constructive

There is no measure of future behavior

Results should match up with your initial theory

You can expect specific alternate assessment scores

relationonship to other information corresponds well with some theory

Concurrent Criteria

Helps to create a shorter more time efficient test is proved to be valid

Must make sure that the time between the two tests is minimal for better idea of validity

You must compare the two test scores to see if the new test is valid

Measured by administering both the new test and the established test to a group of respondents

Given at the same time as the measure to be validated

Content

There arent any numerical formulas with content validity

Content validity is the easiest to measure

You use logic or common sense to assess validity

Insures that the learning objectives and the assessment items match each other
