The Test of Nonverbal Intelligence- Fourth Edition is a practical, easy-to-use, norm-referenced instrument that measures an individual's intelligence. The administration and response format are pragmatic with simple oral instructions, requiring test takers to answer only with simple but meaningful gestures such as pointing, nodding, or blinking. This test is ideal for those who have language, hearing, or motor impairments, or are not familiar with mainstream American culture. Data was collected from a normative sample of 2,272 people residing in 33 states.
The TONI-4 has two equivalent forms: Form A and Form B. Each form consists of 60 items, all of which are abstract/figural (i.e., void of pictures or cultural symbols), thus educational, cultural, or experiential backgrounds will not adversely affect test results. All items are arranged in easy-to-difficult order. Each item contains one or more of the eight salient characteristics:
Easier items contain one or two characteristics while more difficult items contain several. Both forms can also be used for research purposes and periodic reevaluation.
COMPLETE TONI-4 KIT INCLUDES: Examiner's Manual, Picture Book, Critical Reviews and Research Findings (1982-2009), 50 Form A Answer Booklets and Record Forms, 50 Form B Answer Booklets and Record Form, all in sturdy storage box. (©2010)
