What is test validity and test validation?
Tests themselves are not valid or invalid. Instead, we validate the use of a test score.
Tests are pervasive in our world. Tests can take the form of written responses to a series of questions, such as the paper-and-pencil SAT™, or of judgments by experts about behavior, such as those for gymnastic trials or for a work performance appraisal. The form of test results also vary from pass/fail, to holistic judgments, to a complex series of numbers meant to convey minute differences in behavior.
Test validity, or the validation of a test, explicitly means validating the use of a test in a specific context, such as college admission or placement into a course. Therefore, when determining the validity of a test, it is important to study the test results in the setting in which they are used. In the previous example, in order to use the same test for educational diagnosis as for high school graduation, each use would need to be validated separately, even though the same test is used for both purposes.
