The present study assessed the Kaufman Assessment Battery for Children, Second Edition (KABC‐II) in relation to the synthesized Cattell–Horn–Carroll (CHC) theory of intelligence with a preschool sample. Participants were 200 preschool children between four and five years of age. A confirmatory factor analysis (CFA) was conducted, and different variations of the CHC model were examined to determine which provided the best representation of the proposed underlying CHC constructs tested by the KABC‐II. The models included one similar to Spearman's g , a contemporary two‐stratum model consisting of fluid and crystallized intelligence (Gf‐Gc model), and a synthesized CHC broad factor + g model. The last was the empirically validated theory of interest in this study. Results of the CFA revealed that the broad factor + g CHC model was the best overall design to explain KABC‐II results. © 2009 Wiley Periodicals, Inc.
