The CTONI-2 is particularly appropriate for use with 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. Normed The CTONI-2 is a popular norm-referenced test that uses nonverbal formats to measure general intelligence of children and adults whose performance on traditional tests might be adversely affected by subtle or overt impairments involving language or motor abilities.

| Description: | The Comprehensive Test of Nonverbal Intelligence – 2nd Edition (CTONI-2) is a norm-referenced test that uses nonverbal formats to measure general intelligence of children and adults whose performance on traditional tests might be adversely affected by subtle or overt impairments involving language or motor abilities. The CTONI-2 measures analogical reasoning, categorical classification, and sequential reasoning, using six subtests in two different contexts: Pictures of familiar objects (e.g., people, toys, animals,) and geometric designs (e.g., unfamiliar sketches and drawings). Results are reported as standard scores, percentile ranks, and age equivalents. The six subtests are: Pictorial Analogies; Geometric Analogies; Pictorial Categories; Geometric Categories; Pictorial Sequences; and Geometric Sequences. All new normative data were collected in 2007 and 2008. Floor effects have been eliminated and study of item bias has been expanded. |

The CTONI-2 measures:
- Analogical Reasoning
- Categorical Classification
- Sequential Reasoning
These areas are divided into six subtests in two different contexts:
Ctoni 2 Scoring Tables
- Pictures of familiar objects
- Geometric Designs
Six 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 CTONI-2 was normed on a large (2827) representative national sample that was stratified by age. The reliability coefficients of its composite are in the .90s with a few in the high .80s. It correlates with most well-known intelligence tests in the high .70s. New oral instructions for common non-English languages in the United States have been provided.
The CTONI-2 Complete Kit includes a Manual, 1 package of Examiner Record Forms, and 1 each of the Analogies, Categories, and Sequences Picture Books.
