Comprehensive Test of Nonverbal Intelligence-Second Edition
Donald D. Hammill, Ed.D. , Nils A. Pearson, Ph.D. , J. Lee Wiederholt, Ph.D.
Measure nonverbal reasoning abilities in individuals 6 to 89 years
Overview
Overview
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).
Key Features:
- Includes an expanded study of item bias
- No oral responses, reading, writing, or object manipulation are required
- Verbal instructions are available for a variety of non-English languages
