Wechsler Nonverbal Scale of Ability

D. Wechsler & Jack A Naglieri

A nonverbal measure of ability for anyone. Especially designed for culturally and linguistically diverse groups.
The WNV is ideal for psychologists who need a nonverbal measure of ability for individuals who aren’t English-language proficient, or have other language considerations.

Designed for Linguistically Diverse Populations

When language poses a barrier to typical administration, or where traditional intellectual assessment results would be questionable due to language-related difficulties, the WNV is appropriate for all individuals.
