CTONI - The Comprehensive Test of Nonverbal Intelligence

Nonverbal Intelligence - Why Nonverbal Assessments Are Needed : In general, nonverbal assessments attempt to remove language barriers in the estimation of a student's intellectual aptitude. This is especially helpful in assessing students without speech or who have limited language ability, those with deafness or who are hard of hearing, and those with English language limitations. To accommodate students with speech or language limitations, the student can be administered either orally or by using pantomime.

The CTONI Measures Specific Skills: The CTONI measures several types of nonverbal reasoning skills. Through pictures and pointing responses, students solve problems using analogies, classification skills and logical sequences. Analogies assesses the student's ability to recognize common features between unlike objects. Categorization tasks require students to identify common attributes for sorting pictured objects. The student's ability to understand logical sequences is also assessed. Test items measure both concrete and abstract concepts.
