The Comprehensive Test of Nonverbal Intelligence-Second Edition (CTONI-2™) is an unbiased measure of nonverbal reasoning abilities in individuals for whom most other mental ability tests are either inappropriate or biased. Results of the CTONI-2 are useful for estimating the intelligence of individuals who experience undue language or fine motor skill difficulties.
The CTONI-2 measures analogical reasoning, categorical classification, and sequential reasoning, using six subtests in two different contexts: pictures of familiar objects (e.g., toys, people, animals) and geometric designs (unfamiliar sketches and drawings).

The CTONI-2 includes an Analogies Book, a Categories Picture Book, and a Sequences Picture Book. Profile/Examiner Record Forms are used to record responses for the handscored format.
The CTONI-2 was normed on a large representative national sample of 2,827 individuals. The normative data 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.
