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.

Innovative Pictorial Directions make administration easy and effective

  • No need to pantomime instructions
  • Native language of the examinee is irrelevant to performance
  • Flexible standard administration allows help when appropriate

WNV was specifically created for:

  • Individuals for whom English is not a first language
  • Hard of hearing or deaf individuals
  • Individuals with language difficulties or disorders
  • Individuals who may be eligible for special services and support
  • High functioning individuals from linguistically diverse populations

Ideal for low incidence disorders such as:

  • Cerebral palsy
  • Aphasia
  • Expressive language disorders
  • Receptive language disorders
  • Physically disabilities / complex needs
  • Specific language impairments

Language diversity doesn’t mean having to use several different tests

No need for adapted administration for use in different countries or with individuals from different countries Supplemental directions in several languages

Ideal for use in schools with individuals from multiple language backgrounds

Flexibility with the choice of Full Battery or Brief Version

Both versions are available within each WNV kit. Different sets of subtests are administered according to the examinee’s age – each measures general ability in a different way.

Full battery subtests include:

  • Matrices
  • Object Assembly
  • Coding
  • Recognition
  • Spatial Span
  • Picture Arrangement

Brief version

Two subtests
Yields a single ability score
