Inside Urban Charter Schools offers an unprecedentedly intimate glimpse into the world of charter schools by profiling five high-performing urban charter schools serving predominantly low-income, minority youth in Massachusetts. Interviews, focus groups, and classroom observations conducted over the course of two years flesh out rich and colorful portraits of daily life in these schools. Using an analytic framework grounded in research on nonprofit management and effective schools, the authors show that these schools excel along the organizational dimensions of structure, systems, human resource strategies, culture, and clarity of mission. By raising provocative questions for parents, educators, policymakers, and scholars, the book makes a powerful contribution to important conversations about the purpose of K–12 schooling in the twenty-first century and what it will take to enable all schools—whether charter or traditional—to successfully educate all students.
