The TOPV has two subtests: Expressive Vocabulary and Receptive Vocabulary. Combine the results of the two to create a composite, the General Vocabulary Index.
Use the test results to (a) identify children with oral language disorders, (b) diagnose early semantic ability, (c) compare receptive and expressive vocabulary knowledge, (d) monitor language intervention progress, and (e) do research.
The TOPV was normed on a 29 state, nationally representative sample of 1,190 children, ages 2;0 through 5;11. It yields percentile ranks, scaled scores, age equivalents, and an index score. TOPV has strong internal consistency and test-retest reliability (coefficients ranging from .82 to .97). It correlates highly (.73 Very Large) with popular criterion measures of spoken vocabulary. Studies report diagnostic accuracy relating to the test’s sensitivity (.73), specificity (.79), classification accuracy (.76), and receiver operating characteristic/area under the curve (ROC/AUC; .82).
