The Framework for English Language Proficiency Development Standards was developed by the Council of Chief State School Officers (CCSSO) to communicate to English Language Learners (ELL) stakeholders the language practices that all ELLs must acquire in order to master the Common Core State Standards (CCSS) and Next Generation Science Standards (NGSS). The goal is to ensure well crafted English Language Proficiency (ELP) standards so that students receive the rigorous education they need to graduate high school and be college ready.
