The factor structure of the "KeyMath--Revised Normative Update" (KMR-NU) "Form A" was analyzed using data from a sample of 130 students. The KMR-NU is composed of 13 subtests that are purported to measure three important aspects of math ability: Basic Concepts, Operations, and Applications. A confirmatory factor analysis employing scaled scores from the 13 subtests was used to evaluate the model fit of the hypothesized three-factor model. The results of the analysis did not support the three-factor model. Follow-up exploratory factor analyses were conducted to determine if other models might provide a better model fit for the data. The results were consistent with the only factor-analytic study conducted with a previous version of the KMR-NU (Walker & Arnault, 1991), which suggested that the Total Score was the only score that should be used. (Contains 4 tables and 1 figure.)
