An innovative new measure, the VAS-E and VAS-R present full-color photographs to measure the breadth of an individual’s vocabulary and oral language development. A complementary pair of norm-referenced tests designed for simple administration and scoring, the VAS-E and VAS-R can be used individually or in combination throughout an individual’s life span.
Expressive

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-E can be administered in 15-20 minutes.
Receptive

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. The VAS-R can be administered in 15-20 minutes.
Features and benefits

Choose between digital or paper stimuli. The VAS stimulus books are available digitally, for use on your tablet, or on paper, for traditional administration.
Evaluate with greater ecological validity. Full-color photographs provide the highest degree of realism possible. Beyond simply improving aesthetics, using photographs instead of drawings may allow for a more accurate assessment of an individual’s vocabulary.
Obtain an enhanced skill assessment. Composite and discrepancy scores enhance your ability to interpret expressive and receptive scores. When both the VAS-E and VAS-R are administered, examiners can calculate a Vocabulary Composite Score as well as an Expressive-Receptive Discrepancy Score.
Monitor effectiveness of interventions. Reliable change scores enable you to measure growth in vocabulary or oral language over time and in response to targeted interventions. They also make the VAS ideal for the evaluation of language impairments as the result of injury or disease (e.g., dementia, aphasia, TBI). Equivalent, co-normed forms reduce the occurrence of practice effects that can result from repeated administrations. Plus, there are few overlapping words between the VAS-E and VAS-R, a significant improvement over existing vocabulary tests.
Assess throughout the lifespan. Offering both age- and grade-based norms, the VAS-E and VAS-R are suitable for evaluating individuals ages 2.5 to 95 years in clinical, school, occupational, and industrial settings. Normative data are based on a sample of 2,678 individuals representative of the 2009 U.S. Census in terms of age, gender, ethnicity, and education level. Age-based norms are provided for 28 different groups, and grade-based norms are provided for children and adolescents enrolled in pre-kindergarten to Grade 12.
Review data on multiple validity groups. Validity groups included children and adults with speech impairment; individuals with language delay, language disorder, dementia, hearing impairment, reading disability, intellectual developmental disorder, emotional disturbance (ED), ADHD, autism spectrum disorder, and traumatic brain injury (TBI); and gifted and talented individuals.
Evaluate hard-to-test individuals. Ideal for use with nonreaders or with people who have reading or written language impairments, the VAS requires no reading or writing. The response format places a low demand on motor skills.
Get a Fast Guide, too. The VAS Fast Guide, meant to quickly and efficiently orient you to the administration and use of the test, is included with your purchase of either the print or digital Professional Manual.

Digital materials are available!

Stimulus books are available for download to your iPad®, making assessment even more convenient. The e-manual also includes a digital version of the Fast Guide. Tailor your VAS package to your practice by selecting among digital and print versions of the various VAS components.
