Vocabulary Assessment Scales–Expressive and Receptive
by Rebecca Gerhardstein Nader, PhD
Norms
Based on a sample of 2,678 individuals representative of the 2009 U.S. Census; Norms are provided for 28 age groups and 13 Grades (K to 12)
Benefit
Measures vocabulary and oral language development across the lifespan
Scores
VAS-E or VAS-R separately: standard score, confidence interval, percentile rank, and grade and age equivalentsVAS-E and VAS-R combined: Vocabulary Composite Score, Expressive-Receptive Vocabulary Discrepancy, and Reliability Change Score
Format
Individually administered with a response format requiring no reading or writing
These new norm-referenced tests use full-color photographs to measure the breadth of an individual’s vocabulary and oral language development. Designed with simplicity and brevity in mind, the VAS-E and VAS-R can be used separately to measure Expressive or Receptive Vocabulary, or together for a more comprehensive look at oral language development.
Each test includes a Form A and an equivalent Form B for retesting, making it easy to identify progress over time. This is particularly valuable for use in school-based reading programs and rehabilitation or other medical settings where development is monitored. Since individuals respond by speaking, the VAS-E and VAS-R can be used with a variety of people, including those with reading, writing, or motor difficulties.
