Omar is a school superintendent who is trying to improve the selection process for teachers in his school district. Before implementing the selection test as a deciding factor in the hiring process, Omar decides to give the test to current teachers to see if the test can accurately differentiate the top performers from the mediocre and poor performers. After that, he compares the scores of the teachers to their performance ratings on appraisals. In this scenario, Omar is assessing the of the test. a. concurrent validity b. predictive validity c. test-retest validity d. face validity

B. Predictive Validity

Explanation:

Predictive Validity is a type of validity or form of evidence, often used in sociology, psychology or any form of behavioural science test, in which the purpose is to defend the use of a test for predicting other outcomes.

In other words, it is a method of developing validity evidence for employment tests in which a test is given to present employees, then a rating of those employees' job performance that are gathered or obtained independently of the test are used to predict other outcomes.

Predictive validity is however shown when a test correlates well with a measure that has previously been validated.

Hence, in this case, Omar is assessing the Predictive Validity of the test.
