title: A description of the comprehensive test of nonverbal intelligence.
abstract: The Comprehensive Test of Nonverbal Intelligence, or CTONI, has become an essential compliment to the traditional tests of intelligence, such as the WISC-III, DTLA-3, and the Binet. The CTONI provides examiners with a measure of nonverbal reasoning that requires no spoken language or complex motor skills. The CTONI has been proven to be unbiased with regard to gender, minority, or disabling condition. Finally, it is possible to estimate the intelligence of people without the contamination of social, ethnic, or disability bias.
