Correct Response: A. In 2012, as part of the Rethinking Equity and Teaching for English Language Learners (RETELL) initiative, the Massachusetts Board of Elementary and Secondary Education adopted the WIDA English Development Standards Framework. Since then, school districts have been asked to integrate the WIDA ELD Standards into content-area curricula and use the framework as a starting point to help students, families, teachers, and administrators in advocacy efforts to improve English learner' access to grade-level, standards-based academic content. The WIDA ELD standards promote social and instructional language and academic language proficiency in language arts, mathematics, science, and social studies. B and C are not correct because the WIDA ELD Standards are not a set of teacher competencies and knowledge requirements for an ESL or SEI endorsement (B), nor are they an evaluation tool for analyzing the integration of reading skills into content-area curricula (C). WIDA states specifically that the ELD standards are not a scope and sequence of language skills (D).
