In spite of decades of school reform, the achievement gap between English learners and English-proficient students has narrowed little. This book introduces a Reform Sustainability Framework that focuses on the examination of fundamental school structures required to ensure English learner success while guiding the school leader in handling the reform terrain deftly. This reform-navigation tool identifies patterns and trends in the deployment of a reform and subsequently allows leaders to make necessary adjustments to extend, accelerate, or terminate a given reform. Bridging the English Learner Achievement Gapoffers a compelling, research-grounded way for schools with an English learner population to successfully educate their students. This book: highlights the challenge of meeting the academic needs of English learners; introduces a step-by-step process for educators at any level to ensure reform sustainability; and examines the processes, tools, and structures needed to anchor successful school reform.
