CASLS empowers educators with the tools to research their own interest topics to improve second language teaching and learning. Through SLA Web, teachers and researchers can access students’ writing and speaking samples in French, German, Japanese, and Spanish to answer questions about how students acquire and use another language.

CASLS collected the student data through the administration of the Standards-based Measurement of Proficiency (STAMP). Researchers can search SLA Web on a number of parameters, including school level, class level, proficiency level, and immersion or heritage status.

CASLS partners with the Dr. Susan Guion and Dr. Jacquelyn Schachter of the UO Department of Linguistics to provide this service to researchers and educators. A grant from the U.S. Department of Education International Research and Studies (IRS) supports development of SLA Web.
