The guide is intended to clarify and define a renewed vision for high-quality, coherent, and rigorous instruction for English Language Learners (ELLs)--focusing on the areas of English language arts (ELA) and English language development (ELD)--and to provide guidance in evaluating and selecting appropriate ELA/ELD instructional materials. It is meant to be a useful guide for educators who teach ELA or ELD to ELLs, and for anyone who is involved in the design, development, and/or selection of curricula, materials, and resources. The document is divided into three sections: (1) Raising Expectations and Instructional Rigor for ELLs; (2) A Comprehensive Approach to ELD; and (3) Evaluating Instructional Materials: A User's Guide.
