= makes suggestions to improve the test


What is content validity?

= allows you to remove poor areas and change items as well as adding in missing items


What is concurrent validity?

Have 2 sets of scores, one from the new test and one from a test already validated = should correlate
BUT old test may not be valid


What is predictive validity?

- correlation of two sets of scores taken at different times
Improved: adding further predictors so controlling for other factors e.g parental support
