Ninety‐four college students were administered the GAMA and KAIT. GAMA IQs were significantly and moderately correlated with KAIT Fluid, Crystallized and Composite IQs, supporting the convergent validity of this instrument. Although significant correlations between measures emerged and nonsignificant differences were found between mean scores across these instruments, GAMA IQ scores did not accurately predict KAIT Composite IQ scores when GAMA IQ scores were compared to KAIT Composite IQs. Similarly, when the sample was divided into two groups by ability level, GAMA IQs accurately estimated the intelligence for individuals of Average and Below Average intelligence, but underestimated the KAIT Composite IQ scores by 4 points for the Above Average group. Implications of the findings are discussed and suggestions for future research are provided. © 2002, Wiley Periodicals, Inc.
