SLA Web

Ever wonder if heritage learners can really speak their native language better than they can write it? Want to compare your students' performances with their peers across the country?

SLA Web allows educators and researchers to ask their own questions about student performance and investigate the answer. SLA Web has two tools: performance by the numbers, specifically designed for educators, and the corpus tool, targeted for second language acquisition researchers.

SLA Web is available free of charge to the foreign language community.

  • Graphs scores from French, German, Japanese, and Spanish test administrations
  • Includes reading, writing, and speaking results
  • Shows test results by language of study, native language, and grade
  • Includes demographic data such as age and years of study
  • Contains data from nearly 20,000 test administrations across the country

Corpus Tool: For Researchers

  • Includes responses from speaking and writing prompts in French, German, Japanese, and Spanish
  • Contains responses coded and analyzed using software developed at Carnegie Mellon University
  • Searchable by 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.
