If the SMEs all give the test high ratings, then it has construct validity. Therefore, the test has predictive validity. External validity refers to whether the results of a study generalize to the real world or other situations. Scores on the two tests are compared by calculating a correlation between the two. Formative assessments tend to be more relaxed. This can be done by showing that a study has one (or more) of the four types of validity: content validity, criterion-related validity, construct validity, and/or face validity.
