PTONI: Primary Test of Nonverbal Intelligence

Use to identify both severe intellectual deficits and superior cognitive intelligence.

Testing Time: 5 to 15 minutes
Administration: Individual

The Primary Test of Nonverbal Intelligence (PTONI) is a theoretically sound, research-based method of assessing reasoning abilities in young children. Psychologists, diagnosticians, special educators, speech-language pathologists, and other professionals can use this test to identify both severe intellectual deficits and superior cognitive intelligence; help estimate future school success based on family history, educational background, and personality traits; and study a wide range of researchable topics and issues.

The PTONI was normed on a culturally and ethnically diverse demographic sample of 1,010 children, residing in 38 states. It is unbiased, quick, accurate, and cost-efficient. Testing takes approximately 5 to 15 minutes. Minimal oral directions and a pointing-response format make it one of the simplest and easily understood of all nonverbal intelligence tests designed for young children.

The nonverbal format of the PTONI is especially appropriate for testing children who typically are not verbally or motorically well  developed.  Furthermore, directions in eight alternative languages  are provide for the PTONI making it an appropriate assessment of   intelligence for children from diverse language backgrounds.

This test is composed of an Examiner’s Manual, a Picture Book with easel backing, and an Examiner Record Form.  The test format requires a child to look at a series of pictures on each page in the Picture Book and point to the one picture that does not belong with the others. Items are arranged in order of difficulty. Early items measure lower order reasoning (e.g., visual and spatial perception). Later items measure higher order reasoning abilities (e.g., analogical thinking, sequential reasoning, and categorical formulation). A child’s performance is recorded as a standard score (called the Nonverbal Index), a percentile rank, and an age equivalent.

Complete PTONI Kit Includes: Examiner’s Manual, Picture Book with Easel, and 25 Examiner/Record Forms, all in a sturdy storage box. (© 2008)
