Document Summary
Agreement between a test score or measure and the quality it"s believed to measure. They made many subcategories of validity and definitions of it blossomed term began to lose meaning. Made book called standards and this listed possible definitions of validity: validity is evidence for inferences made about a test score, 3 types of evidence construct-related, criterion-related, and content-related. Face validity mere appearance that measure has validity. We have it if items seem to be related to perceived purpose of test. Doesn"t offer evidence to support conclusions from test scores so it"s not really a form of validity but it is still useful motivates test takers because they see test is relevant. Content validity evidence greatest concern in educational testing. Only type of evidence besides face validity that"s logical rather than statistical. Need expert judgment to determine content validity because you have to pay attention to the tiniest details for each item, e. g. wording.
