This article reviews Test of Nonverbal Intelligence-Fourth Edition (TONI-4), an individually administered instrument created to assess intelligence. The distinguishing characteristic of the TONI-4 is the nonverbal, motor-reduced format that assesses common elements of intelligence without the confounding effects of motor or linguistic skills. The TONI-4 purports to assess the theoretical construct of fluid intelligence and general intelligence; more specifically, the test aims to measure two components of intelligence: abstract reasoning and problem solving. The TONI-4 evolved from three predecessors to improve the manual, theoretical basis, extension of the ceiling and floor, normative sample size, reliability, and validity. Overall, the TONI-4 is a user-friendly test and is efficiently administered. It is a good alternative to other intelligence tests.
