The Benefit of Full-color, Digital Photos to Measure Intellectual Ability

The VAS offers an alternative measure of overall intellectual ability for students who may have difficulty with traditional IQ tests. It is a picture vocabulary test that uses modern, engaging stimuli to measure expressive and receptive language throughout the age range.

Our In-Person e-Stimulus Books and Kits are convenient, more hygienic alternatives to paper administration that allow you to administer the VAS face-to-face via tablet. Be sure to download our new  white paper prior to administering.

    • The VAS-E presents a single picture along with a verbal prompt (e.g., “What is this?”). Examinees are required to verbally provide a single-word response.
    • The VAS-R presents a set of four picture stimuli and asks examinees to select the picture that best corresponds to the word spoken by the examiner.
    • Scoring is available 24/7 on PARiConnect, our online assessment platform.
