States use a variety of English language proficiency assessments to identify, monitor, and exit ELLs. Most states participate in assessment consortia that unify around English language proficiency standards. The main consortia, including the World-class Instructional Design and Assessment (WIDA), and the English Language Proficiency Assessment for the 21st Century (ELPA21), have developed their own standards that comply with NCLB’s specifications.

States that have not joined the two main consortia use a variety of other English language proficiency assessments.
