Q: What is validation? How do I know if my test is validated?
A: Test validity refers to the extent to which a test accurately measures what it claims to measure. It also refers to the degree of evidence available supporting the interpretations of the tests scores for the intended purpose. Validation is the process of collecting evidence to determine if the test is accurately measuring what it claims to measure and if the test is being used appropriately. There are many different aspects to validity including the way the test is developed, how the test is used, and how scores are interpreted. There is no one best way to conduct a validity study. Ultimately, combined evidence from multiple sources is recommended.
