(CTONI-2) Comprehensive Test of Nonverbal Intelligence-Second Edition
Ages: 6.0 through 89.11 years
Administration: Individual; 1 hour
Ideal for children and adults whose performance on traditional intelligence tests might be adversely affected by language or motor impairments, the CTONI-2 is a completely nonverbal assessment (requires no oral responses, no reading/writing, and no object manipulatives). The CTONI-2 is particularly appropriate for people who are bilingual, non-English speaking, socially or economically disadvantaged, deaf, language disordered, or physically limited. The test requires no oral responses, no reading or writing, and no object manipulation. All the examinee has to do is point to his or her selected response.
The CTONI-2 measures analogical reasoning, categorical classification, and sequential reasoning throughout six subtests. Its six subtests assess these abilities in two ways: First by using pictures of familiar objects and then by using geometric designs.
CTONI-2 Subtests:
• Pictorial Analogies • Geometric Analogies
• Pictorial Categories • Geometric Categories
• Pictorial Sequences • Geometric Sequences
Results are reported as standard scores, percentile ranks, and age equivalents. The test was normed on a large (~2,827) representative national sample that was stratified by age. The reliability coefficients of its composite are mostly in the .90s with a few in the high .80s. It correlates with most well known intelligence testing in the high .70s. Considerable other validity evidence is provided in the manual.
