Episode 4

"This report didn’t just explain my child, it explained our whole life.’ That’s the power of assessment."

Renee Testa, Psychologist

Listen to Renee's story

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.

WNV is a valid tool for use with low incidence disorders such as cerebral palsy, aphasia, physically-/multiple-handicapped, and autism spectrum disorders.

Benefits

  • No need to pantomime of instructions.
  • Native language of the examinee is irrelevant to performance.
  • Deploy full battery or brief version of the tool according to need and offer help, when appropriate, with flexible standard administration.
  • Support Spanish-dominant examinees when no Spanish-speaking clinician or translator is available.
  • Meet current IDEA requirements.

Features

Both a Full Battery and Brief Version of WNV are available. The Full Battery includes the following subtests: Matrices, Objective Assembly, Coding, Recognition, Spatial Span, and Picture Arrangement. The Brief Version includes two subtests and yields a single ability score.

WNV Test Administration

With supplemental directions in several languages, WNV is ideal for use in schools with individuals from multiple language backgrounds, including:

  • 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.
