This study examined the construct validity of the Comprehensive Test of Nonverbal Intelligence (CTONI) in two separate investigations. The first study examined criterion-related evidence of validity across racial/ethnic groups on the CTONI and the Woodcock-Johnson Psychoeducational Tests of Achievement (3rd edition). The second study examined the comparability of the standard and computerized forms of the CTONI. Results of the first study revealed that the CTONI overall score did not correlate significantly with reading achievement and correlated moderately with math achievement. The CTONI also showed significant racial/ethnic group differences, despite the absence of these differences on achievement. Results of the second study revealed that average scores on the standard form of the CTONI were significantly higher statistically than those on the computerized form. Correlations between raw scores on the computerized form of the CTONI and age were statistically significant, although generally low. In sum, results of this research raise concerns and questions about the validity of the CTONI. The CTONI should be used with caution, if at all, until further research is conducted.
