Abstract:
The revised form of the Expressive One-Word Picture Vocabulary Test assesses a child's expressive single-word picture vocabulary and can be used as a basal estimate of the child's verbal intelligence. It can also provide information about speech defects, possible learning disorders, a bilingual child's fluency in English, auditory processing, and auditory-visual-verbal association ability. The test is available in both English and Spanish and was designed for children from 2-12 years. Although untimed, it usually takes 7-15 minutes to administer. The test has been restandardized and renormed based on a new sample of 1,118 children at various age levels whose primary language is English. Scores are given as Age Equivalents, Standard Scores, Scaled Scores, Percentile Ranks, and Stanines. The Kuder-Richardson formula (KR20) shows that split-half reliability ranges from .84 to .92. No concurrent validity was assessed.
