Types of Validity

Content Validity

Criterion- related Validity

Construct Validity

Predictive Validity

Page 8: validity its types and importance

Content Validity

A type of validation that refers to the relationship between a test and the instructional objectives

Page 9: validity its types and importance
Page 10: validity its types and importance

The evidence of the content validity of your test is found in the Table of Specification.

This is the most important type of validity to you, as a classroom

teacher.

There is no coefficient for content validity. It is determined judgmentally, not empirically.

Criterion- related ValidityCriterion- related validity is a type of validation that refers to the extent to which scores from a test relate to theoretically similar measures.

Page 12: validity its types and importance

Construct

Validity

• a type of validation that refers to a measure of the extent to which a test measures a hypothetical and unobservable variable or quality

Predictive

Validity

•refers to a measure of the extent to which a person’s current test results can be used to estimate accurately what that person’s performance or other criterion, such as test scores will be at the later time.

Page 13: validity its types and importance

Concurrent Validity

A type of validation that requires the correlation of the predicator or the concurrent measure with the criterion measure.

The higher the validity coefficient, the better the validity evidence of the test
