Comprehensive Test of Nonverbal Intelligence (CTONI-2)

Looking for an IQ test to non-verbally assess a child’s reasoning and problem-solving skills?

The Comprehensive Test of Nonverbal Intelligence (CTONI-2) is the one you’re looking for. The CTONI-2 is a multiple-choice test, where children can simply point to an option as a response. No oral responses, reading, writing or object manipulation is required.

What does the CTONI-2 measure?

The CTONI-2 measures analogical reasoning, categorical classification and sequential reasoning with subtests in 2 different contexts — pictures of familiar objects and geometric designs. Hence there are these 6 subtests:

Ψ Pictorial analogies
Ψ Geometric analogies
Ψ Pictorial categories
Ψ Geometric categories
Ψ Pictorial sequences
Ψ Geometric sequences

Advantages of the CTONI-2

An advantage of theCTONI-2 is that it requires relatively less time to complete as compared to other intelligence tests. In addition, as non-verbal responses can be used to respond to the questions on the CTONI-2, this test is suitable for children with disabilities or impairments in language or motor abilities (e.g., traumatic brain injury, post-stroke syndrome, deafness, aphasia, autism spectrum disorder, or other language disorders).

However, the CTONI-2 relies heavily on pictures for its questions, and so this test might be less suitable for children with visual impairments. In such cases, we would recommend other intelligence tests, such as the Wechsler Intelligence Scale for Children or Wechsler Abbreviated Scale of Intelligence. The child psychologists at Annabelle Kids are also experienced in administering these cognitive tests.
