The TONI-4, featuring new norms to help ensure proper representation of demographic changes in the U.S. population, offers you an assessment of intelligence, aptitude, abstract reasoning, and problem solving. This language-free test is ideal for evaluating those with questionable or limited language ability.
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.
- TONI-4 provides two equivalent forms, each containing 60 items arranged in easy to difficult order.
- All items are abstract/figural (i.e., void of pictures or cultural symbols); educational, cultural, or experiential backgrounds will not adversely affect test results.
