Is the CRA a valid and reliable assessment tool?
• The CRA is the result of over fifteen years of research and development at John Brown University and Denver Seminary. For the CRA to be of any value it must have reliability and validity. Reliability indicates whether the attribute measured by the testwhatever it isis being assessed in a consistent, precise way. Whether the test is actually assessing what it was designed to measure is addressed by an analysis of the test’s validity. The CRA has good reliability (.800+ alpha) in that it provides dependable and consistent results. • On the other hand, validity refers to a test’s accuracyit measures what it is intended to measure. Evidence for validity comes from showing the association between a test and other variables over time. At this point, the CRA has good Face Validity (whether or not a test looks like it measures what it is intended to measure) and Content Validity (experts agree that test items are an adequate and representative sample of the target domain).
