The Every Student Succeeds Act (ESSA) is a landmark education law enacted in 2015 that aims to ensure all students receive a high-quality education. It replaced the No Child Left Behind Act and shifted more control to states and local districts, allowing them to set their own educational standards and accountability systems. ESSA emphasizes the importance of student achievement and requires states to develop plans to improve educational outcomes for all students, particularly those from disadvantaged backgrounds. The law also promotes greater flexibility in how schools are evaluated and funded, fostering a more tailored approach to education across the country.
