This study examined the underlying constructs measured by the Differential Ability Scales (DAS; C.D. Elliott, 1990a) as they relate to the Cattell‐Horn‐Carroll (CHC) Theory (K.S. McGrew, 1997) of cognitive abilities. The DAS and Woodcock‐Johnson Tests of Cognitive Abilities (WJ‐III COG; R.W. Woodcock, K.S. McGrew, & N. Mather, 2001) were administered to 131 children in grades 3 through 5 who took part in a concurrent validity study included in the Woodcock‐Johnson Tests of Cognitive Abilities , Third Edition , technical manual (K.S. McGrew & R.W. Woodcock, 2001). Confirmatory factor analyses using maximum likelihood estimation were conducted with the AMOS 5.0 (J.L. Arbuckle, 2001) statistical program to evaluate three models of increasing complexity, to compare how well each fit the data set, and to identify the one that best described the underlying constructs measured by the DAS. Results suggested that the synthesized Three‐Stratum CHC Model provided the most parsimonious representation among the three models tested. © 2007 Wiley Periodicals, Inc.
