Data required for evaluating a Criterion Referenced Measurement (CRM) is described with a matrix. The information within the matrix consists of the "pass-fail" decisions of two CRMs. By differentially defining these two CRMs, different concepts of reliability and validity can be examined. Indices suggested for analyzing the matrix are listed with their formula. Using the National Norm Group for the Primary Test of Economic Understanding, three questions were investigated: (1) What indices are consistent across samples?; (2) What indices are giving independent information?; and (3) Are these same indices consistent when sample sizes vary? The procedure and analysis used to obtain answers to the questions are given, and five tables provide the study data. (DB)
