Validity Evidence

In this resource, we seek answers to two important questions. Whether the students tested have disabilities or not, the questions are identical: (1) How valid is our interpretation of a student's test score? and (2) How valid is it to use these scores in an accountability system to make judgments about students’ performance as it relates to a set of content standards? Validity evidence may be documented at both the item and total test levels. This paper focuses only on documentation of validity evidence at the total test level.
