The book "No Teacher Left Behind: The Power is in Our Voices" is urgently needed to address a critical crisis in education-teacher retention, particularly in urban schools. The data on teacher attrition is alarming, with urban schools experiencing an even higher rate of turnover. This issue is not just a numbers problem; it's a crisis that impacts the quality of education, student outcomes, and the overall stability of schools. Urban school leaders are constantly struggling to find and retain teachers, and this book seeks to address this challenge by offering a model of support tailored to the unique needs of urban educators.
