English Language Proficiency Assessment for the 21st Century (ELPA21)


Develops assessments to evaluate k-12 students' proficiency in relation to new English language proficiency standards aligned to college- and career-readiness. ELPA21 is a consortium comprising the Institute's National Center on Educational Outcomes, 10 states, and other organizations who are working together to ensure that the assessments and instructional supports provided to English language learners (ELLs) are accessible for all ELLs, including those with disabilities.
