Summary

    About This Product

    BY DONALD D. HAMMILL, NILS A. PEARSON, AND J. LEE WIEDERHOLT

    Here is a completely nonverbal assessment that’s ideal for children and adults whose performance on traditional intelligence tests might be adversely affected by language or motor impairments. 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.    

    Individually administered in 60 minutes, the CTONI-2 measures analogical reasoning, categorical classification, and sequential reasoning. Its six subtests assess these abilities in two ways—first using pictures of familiar objects and then using geometric designs:

    • Pictorial Analogies
    • Geometric Analogies
    • Pictorial Categories
    • Geometric Categories
    • Pictorial Sequences
    • Geometric Sequences

    The CTONI-2 generates six subtest and three composite scores: Global Nonverbal IQ, Pictorial Nonverbal IQ, and Geometric Nonverbal IQ. All are provided as standard scores, percentile ranks, and age equivalents. The test was standardized on a nationally representative sample of 2,827 individuals between the ages of 6-0 and 89-11. Norms are stratified by age, and this second edition eliminates floor effects.    

    Test items are presented in sturdy, spiral-bound Picture Books, each with a handy easel back. Directions can be given orally to individuals who speak English, Spanish, simplified Chinese, French, Tagalog, Vietnamese, German, or Korean. Gestures can be used with those who are deaf or speak a language not noted above.    

    Easy to administer, fun to take, and free of gender and racial bias, the CTONI-2 allows you to assess the reasoning ability of individuals who would otherwise be difficult to test.
