The assessment is ideal for Spanish-speaking students, English learners, bilingual students, and children enrolled in dual-language programs. Results help identify language strengths, areas for growth, and support educational planning and language development.

School systems throughout the United States use the Woodcock-Muñoz Language Survey III as part of evaluations to better understand a student's language proficiency and to inform instructional and educational 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. It is standardized using a large, nationally representative sample of Spanish-speaking individuals across a wide age range, allowing performance to be compared with that of same-age peers. The assessment provides reliable information about a student's Spanish language proficiency and supports educational decision-making for multilingual learners.
