Critics on both the Left and the Right have charged that the No Child Left Behind Act tramples states’ rights by imposing a federally mandated, one-size-fits-all accountability system on the nation’s diverse states and schools.

In truth, No Child Left Behind (NCLB) gives states wide discretion to define what students must learn, how that knowledge should be tested, and what test scores constitute “proficiency”—the key elements of any educational accountability system. States also set standards for high school graduation rates, teacher qualifications, school safety and many other aspects of school performance. As a result, states are largely free to define the terms of their own educational success.
