The WNV is ideal for psychologists who need a nonverbal measure of ability for individuals who are neither English-language nor Spanish-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
  • Ideal for Spanish-dominant examinees when no Spanish-speaking clinician or translator is available

WNV was specifically created for:

  • Immigrant individuals who are English language learners
  • Hispanic individuals who are neither English-language nor Spanish-language dominant
  • Hard of hearing or deaf individuals
  • Individuals with language difficulties or disorders
  • Individuals who may be eligible for special services and support
  • Gifted individuals from linguistically diverse populations

Ideal for low incidence disorders such as:

  • Cerebral palsy
  • Aphasia
  • Physically-/multiple-handicapped
  • Autism spectrum disorders

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
  • Meets current IDEA requirements

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
