The Comprehensive Receptive and Expressive Vocabulary Test -Third Edition (CREVT-3) is an innovative, efficient measure of both receptive and expressive oral vocabulary. It is a norm-referenced assessment tool used to identify, describe, and quantify oral vocabulary proficiency in children and adults. Specifically, it can be used to identify individuals who are significantly behind their peers in oral vocabulary facility, note discrepancies between receptive and expressive oral vocabulary, document progress in oral vocabulary development as a consequence of intervention programs, and measure oral vocabulary in research studies. Features of the CREVT-3 Two equivalent forms are available All new normative data (N = 1,535) were collected from a demographically representative sample of the 2011 U.S. population ages 5-0 through 89-11 years. Outdated photos (i.e., automobile, truck, mailman, vacuum cleaner, shaver, stove) were replaced with more contemporary photographs. A pronunciation guide for administering both subtests is provided in CREVT-3. Studies showing the absence of gender and ethnic bias have been expanded. The composite score has neither floor nor ceiling effects. Reliability coefficients have been computed by age and by gender, ethnic, racial, and exceptionality subgroups within the normative sample, as well as for the entire normative sample. Numerous validity studies, including sensitivity, specificity, and ROC/AUC, have been provided. Raw scores can be converted to age equivalents, standard scores, percentile ranks, and descriptive terms. Consistently strong reliability and validity evidence provided. CREVT-3 Subtests The CREVT-3 has two subtests. The results of the subtests can be combined to form an overall General Vocabulary Index.
