The TONI-4 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 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.
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: shape, position, direction, rotation, contiguity, shading, size, and movement. Easier items contain one or two characteristics, whereas more difficult items contain several characteristics. Both forms can also be used for research purposes and periodic reevaluation.
