Woodcock-Muñoz Language Survey – Revised Normative Update (WMLS-R NU)

The Woodcock-Muñoz Language Survey – Revised Normative Update (WMLS-R NU; Woodcock, Muñoz-Sandoval, Ruef, & Alvarado, 2005; Schrank, Wendling, & Alvarado, 2010) is an individually administered assessment designed to measure proficiency in oral language, language comprehension, reading, and writing.


Two forms (A & B) are available for English and one form for Spanish; they can be used to assess individuals from 2 through 90 years old. The seven subtests of the WMLS-R English and Spanish forms include Picture Vocabulary/Vocabulario sobre Dibujos, Verbal Analogies/Analogías Verbales, Letter Word Identification/Identificación de Letras y Palabras, Dictation/Dictado, Understanding Directions/Comprensión de Indicaciones, Story Recall/Rememoración de Cuentos, and Passage Comprehension/Comprensión de Textos. These seven subtests are combined in different ways to yield the following 11 cluster scores: Oral Language, Reading-Writing, Broad English Ability, Listening, Oral Expression, Reading, Writing, Language Comprehension, Applied Language Proficiency, Oral Language-Total, and Broad English Ability-Total.

The test manual outlines the following nine purposes for which the test can be used: (a) determining English and/or Spanish language proficiency; (b) determining oral language dominance of bilingual (English and Spanish) subjects; (c) monitoring growth or change in English and/or Spanish language ability; (d) determining eligibility for bilingual education/ESL services; (e) assessing readiness of English language learners for English-only instruction; (f) determining eligibility for accelerated or gifted and talented programs; (g) assisting in educational planning; (h) evaluating program effectiveness; and (i) describing subjects’ language characteristics in research studies (Comprehensive Manual, pp. 5–7). In addition to age and grade equivalent scores, standard scores, and percentile ranks, the WMLS-R also provides a relative proficiency index (RPI) score and a cognitive academic language proficiency (CALP) score. The CALP score can be used to determine if the student is fluent enough for testing administered in English to be valid.
