Today in the United States only 1 in 10 low-income kindergarteners goes on to graduate from college. At a time when education matters more than ever, the U.S. high school graduation rate has dropped from first in the world to the bottom half of rankings for comparable nations. While such sobering facts inform her new book, it is the successes of effective school systems in the U.S. and abroad that the author focuses on to develop a clear and coherent set of policies that can be used to create high-quality and equitable schools. Drawing on her broad experience, Darling-Hammond examines the roots of our modern education system and how the skills required for our 21st century global economy cannot be learned in traditional education systems, which have been in place since the early 1900s. She identifies an “opportunity gap” that has evolved as new kinds of learning have become necessary — a gap where low-income students, students of color, and English language learners often do not have the same access as others to qualified teachers, high-quality curriculum, and well-resourced classrooms. After setting the stage on current conditions in the U.S., Darling-Hammond offers a coherent approach for effective reform, focusing on creating successful systems, inducting and supporting quality teachers, designing effective schools, establishing strong professional practice, and providing equitable and sufficient resources. lays out what the United States needs to do in order to build a system of high-achieving and equitable schools that ensures every child the right to learn.
