The U.S. Department of Education's Office for Civil Rights (OCR) and U.S. Department of Justice (DOJ) released joint guidance on January 7, 2015, reminding states, school districts, and schools of their obligations under federal law to ensure that English Learners (ELs) have equal access to a high-quality education and the opportunity to achieve their full academic potential. In this context, the Office of English Language Acquisition (OELA) at the U.S. Department of Education (the Department) has provided the "English Learner (EL) Tool Kit," a companion to the OCR's and DOJ's "Dear Colleague Letter" (DCL) (see ED578886). The tool kit is designed to help state and local education agencies (SEAs and LEAs) in meeting their legal obligations to ELs and in providing all ELs with the support needed to attain English language proficiency while meeting college- and career-readiness standards. The "EL Tool Kit" is intended primarily for state, district, and school administrators, as well as teachers, but may also inform other stakeholders concerned with the education of ELs. The 10 chapters of the "EL Tool Kit," originally published in serial form over a number of months, correspond to the 10 sections of the January 2015 DCL. Each chapter provides (1) explanations of the civil rights and other legal obligations to ELs; (2) checklists SEAs, LEAs, and schools can use as self-monitoring tools; (3) sample tools that may be used or adapted for use in SEAs, LEAs, and schools to aid with compliance; and (4) additional resources that may provide further relevant information and assistance.
