Test Intelligence in Non-Verbal Clients
The TONI 4 is a language-free nonverbal intelligence test with two equivalent forms that are appropriate for a wide age range. The TONI-4’s nonverbal, motor-reduced format makes the TONI-4 ideal for estimating the cognitive ability and general intellectual functioning of people who were previously hard to test with traditional measures of intelligence. Made for individuals ages 6-89 years
