6-2. Whether you are administering tests or making decisions based on test results, managers need to understand several basic testing concepts. Reliability refers to a test’s consistency, while validity tells you whether the test is measuring what you think it’s supposed to be measuring. Criterion validity means demonstrating that those who do well on the test also do well on the job while content validity means showing that the test constitutes a fair sample of the job’s content. Validating a test involves analyzing the job, choosing the tests, administering the test, relating your test scores and criteria, and cross-validating and revalidating. Test takers have rights to privacy and feedback as well as to confidentiality.
