About This Product
BY STEVEN C. MATHEWS AND LYNDA MILLER
The Test of Preschool Vocabulary (TOPV) measures a child’s ability to recognize and use single words that represent all parts of speech and a variety of basic concepts, including things, events, experiences, temporality, relational and substantive processes, and relative position. The words are presented in order of difficulty, progressing from familiar words and concepts to less familiar ones.
Two subtests, Expressive Vocabulary and Receptive Vocabulary, combine to yield a composite score, the General Vocabulary Index. The TOPV also offers percentile ranks, scaled scores, age equivalents, and an index score. It has strong internal consistency and test–retest reliability (coefficients ranging from .82 to .97) and it demonstrates good validity (.73) with popular criterion measures of spoken vocabulary.
The TOPV is easy to use and appealing to young children. Test results can help:
- Identify children with oral language disorders
- Diagnose early semantic ability
- Compare receptive and expressive vocabulary knowledge
- Monitor language intervention progress
- Conduct research
