The Comprehensive Test of Nonverbal Intelligence (CTONI) is PRO-ED’s new,
unbiased test that measures nonverbal reasoning abilities of individuals for whom most other
mental ability tests are either inappropriate or biased. The CTONI measures analogical
reasoning, categorical classifications, and sequential reasoning in two different contexts:
pictures of familiar objects (e.g., people, toys, and animals) and geometric designs (e.g.,
unfamiliar sketches and drawings). Results of the CTONI are most useful for estimating the
intelligence of individuals who experience undue difficulty in language or fine motor skills,
including individuals who are bilingual, who speak a language other than English, or who are
socioeconomically disadvantaged, deaf, language disordered, motor disabled, or
neurologically impaired. No oral responses, reading, writing, or object manipulation are
required to take the test.
The CTONI contains the following subtests: Pictorial Analogies, Geometric Analogies,
Pictorial Categories, Geometric Categories, Pictorial Sequences, and Geometric
Sequences. The subtests of the CTONI require students to look at a group of pictures or
designs and to solve problems involving analogies, categorizations, and sequences.
Individuals indicate their answer by pointing to alternative choices.

The CTONI yields raw scores, standard scores, percentiles, and age equivalents. The test
also has three composite scores: Nonverbal Intelligence Quotient, Pictorial Nonver-bal
Intelligence Quoitient, and Geometric Nonverbal Intelligence Quotient.
The CTONI was standardized on more than 2,500 individuals from 25 U.S. states,
Canada, and Panama. Characteris-tics of the normative sample have been stratified and
approximate those provided in the 1997 Statistical Abstract of the United States with
regard to gender, geographic region, ethnicity, race, urban/rural residence, and disability.
The reliability of the CTONI has been studied extensively, and evidence relating to content
sampling, time sampling, and interscorer reliability is provided. The reliability coefficients are
all .80 or greater, indicating a high level of test reliability. Evidence of content,
criterion-related, and construct validity also is reported. The CTONI has gone further than
any other test of intelligence to detect and eliminate sources of cultural, gender, racial, and
linguistic bias. The CTONI normative sample is representative relative to gender, race,
social class, language spoken in the home, and disability. Convincing evidence is presented
in the manual to show that the CTONI items contain little or no bias for the groups studied.

Ctoni 2 Scoring Tables
The CTONI-2 measures:
- Analogical Reasoning
- Categorical Classification
- Sequential Reasoning
Ctoni 2 Manual Pdf
These areas are divided into six subtests in two different contexts:
- 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.
