The English Learners (EL) collaborative constitutes the only national, sustained forum among state education agencies, researchers, policy experts, and partners on issues of standards, assessment, accountability, and policies for English Learners. The EL Collaborative explores issues of policy implementation, particularly focusing on college and career-ready academic standards and state English Language Proficiency (ELP) standards, aligned assessment systems, and state policies that affect instruction, curriculum, professional supports, and leadership for ELs.
