Now with expanded norms (ages 2-0 through 70+), this edition is intended for use with and was normed on a bilingual population of individuals who speak Spanish and English with varying levels of proficiency. Because examinees are permitted to respond in either language, the test measures total acquired vocabulary; it is not a test of language proficiency, since language includes grammar and syntax, as well as vocabulary. Norms are separate from the English 4th edition of the EOWPVT. The Spanish-bilingual edition (SBE) tests are co-normed, allowing for a comprehensive evaluation of a person's naming abilities.
