About Avant STAMP

The Avant STAMP™ (STAndards-based Measurement of Proficiency) language assessment was originally created at the University of Oregon’s Center for Applied Second Language Studies (CASLS). 

Its purpose is to improve language-learning outcomes, support excellence in language programs, and enable language credentialing.

Avant STAMP is recommended for college credit by the American Council on Education (ACE), the same educational body that has provided credit recommendations to institutions of higher education for College Board Advanced Placement (AP) Examinations, Cambridge Assessments, and ACT subject tests. This provides opportunities for students to earn credit or be placed in higher-level courses to advance their language skills.

Universities across the U.S. are recognizing Avant STAMP and creating pathways to higher education for language learners everywhere.
