Wechsler Nonverbal Scale of Ability

Abstract

The Wechsler Nonverbal Scale of Ability (WNV) was explicitly designed to provide a nonverbal measure of general ability that would be appropriate for a wide variety of culturally and linguistically diverse populations. The selection of tests that are described as nonverbal in conjunction with Pictorial Directions and oral directions in five languages provides a unique approach to measuring general ability. The evidence provided in this chapter supports the utility of the test for fair assessment of cognitive ability of those from culturally diverse backgrounds as well as those with language differences or deficiencies as well as those who are deaf or hard of hearing. The research provided in the test manual provides a base to support the use of the instrument but additional research is needed, especially regarding the utility of the instrument within diverse clinical environments.
