•Content validity= How well the test samples the content area of the identified construct (experts may help determine this) •Criterion-related validity= Involves the relationships between the test and the external variables that are thought to be direct measures of the construct (e.g., a When a test has content validity, the items on the test represent the entire range of possible items the test should cover. Content validity is ordinarily to be established deductively, by defining a universe of items and sampling systematically within this universe to establish the test. Indeed, if the test is a work sample, the behavior represented in the test may be an end in itself.

Each test contains items and a close scrutiny of test items will indicate whether the test appears to measure the subject matter content and the mental functions of the teacher wishes to test. Content validity requires the use of recognized subject matter experts to evaluate whether test items assess defined content and more rigorous statistical tests than does the assessment of face validity. What is implied by saying that a test has “predictive” validity is thar the test scores can with so me useful degree of objective valid-ity be used to estimate a future criterion, whereas “concurrent” validity pertains to the test’s correlation with a contemporaneous criterion.
