Given the paucity of research describing the use of the TONI-3 with urban children with disabilities, a brief review of the literature was conducted. While little relevant research was identified, the use of the TONI-3 was supported in a number of diverse settings. This paper also describes a study designed to examine the validity of the Test of Nonverbal Intelligence: Third Edition. TONI-3 IQs, WISC-III FSIQs and KTEA N/U-Comprehensive scores were compared and mean TONI-3 IQs were significantly higher than WISC-III PIQs, VIQs, and FSIQs, and K-TEA Reading and Mathematics Composite scores. Intercorrelations computed among TONI-3 IQs, WISC-III IQs, and K-TEA Reading and Math Composite scores indicated moderate relationships between TONI-3 IQs and WISC-III IQs (r = 0.591, 0.483, 0.591, respectively), and modest relationships with K-TEA Composite Scores (r = 0.328, Reading, r = 0.426, Mathematics, and r = 0.383, Total Battery.
