Test of Non-Verbal Intelligence – Fourth Edition(TONI-4)
Non-verbal intelligence testing designed for accuracy and accessibility
The TONI-4 is a well-respected assessment tool designed to measure a person’s general intelligence without using language. It is especially helpful for individuals who may have difficulties with speaking, reading, or writing, as it uses visual problem-solving tasks like patterns and puzzles instead of words. This test is suitable for children, teenagers, and adults (ages 6 to 89) and is often used when a fair, non-verbal measure of intelligence is needed.
