The present investigation examined the validity of the Comprehensive Test of Nonverbal Intelligence (CTONI) with the Woodcock‐Johnson III Tests of Cognitive Abilities (WJ‐III COG) by administering these instruments in counterbalanced order to 60 college students. Results indicated that the mean CTONI NIQ score was not significantly different from the mean WJ‐III COG General Intellectual Ability (GIA) score. However, mean score differences were found between the CTONI NIQ and the WJ‐III COG Verbal Ability, Thinking Ability, Comprehension‐Knowledge, and Fluid Reasoning cluster scores. Although the correlations between the CTONI and the WJ‐III COG cluster scores were generally of small magnitude, the CTONI Geometric Nonverbal IQ composite score demonstrated construct specificity, whereas the CTONI Pictorial Nonverbal IQ scale did not. The implications of the findings are discussed and practitioners are asked to use caution when using this instrument to assess the fluid reasoning abilities of college students. © 2007 Wiley Periodicals, Inc.
