Woodcock-Muñoz® Language Survey III: Bilingual Language Proficiency Assessment (English & Spanish)

The Woodcock-Muñoz® Language Survey III (WMLS III) is a nationally recognized assessment designed to measure language proficiency in both English and Spanish. By evaluating listening, speaking, reading, and writing skills in each language, the assessment provides a comprehensive picture of a student's bilingual language development. It is ideal for English learners, Spanish-speaking students, bilingual students, and children enrolled in dual-language or immersion programs.

Assessing both languages helps identify a student's linguistic strengths, determine language dominance, distinguish language differences from potential learning concerns, and provide meaningful information to support educational planning. School systems throughout the United States use the Woodcock-Muñoz Language Survey III as part of evaluations to better understand bilingual language development and inform instructional decisions.

A Research-Based Assessment

The Woodcock-Muñoz Language Survey III was developed by renowned assessment experts Richard W. Woodcock, Ana F. Muñoz-Sandoval, Kevin S. McGrew, and Nancy Mather. The English and Spanish forms are designed to work together, allowing professionals to compare language abilities across both languages using nationally representative norms. This provides reliable information about a student's bilingual language proficiency and supports educational decision-making for multilingual learners.
