The document outlines the ESEA flexibility program which provides states flexibility from certain requirements of the No Child Left Behind Act in exchange for rigorous and comprehensive state-developed plans designed to improve educational outcomes for all students, close achievement gaps, increase equity, and improve the quality of instruction. Key aspects of the flexibility include setting ambitious achievement goals, developing differentiated accountability systems, evaluating teachers and principals, and supporting school improvement efforts. The flexibility aims to build on state and local reform efforts already underway.
