The Test of Nonverbal Intelligence, Fourth Edition (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 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.
In addition to English, included are instructions in seven other major foreign languages: Spanish, French, German, Chinese, Vietnamese, Korean, and Tagalog.
