Adequate Yearly Progress (AYP) is the accountability component of the No Child Left Behind Act of 2001.Under NCLB, states are required to establish a definition of Adequate Yearly Progress (AYP) that each district and school is expected to meet.Schools that do not make adequate yearly progress will be identified for increasingly rigorous sanctions designed to bring about meaningful change in instruction and performance. Further, students in low-performing schools will have the option to transfer to other public schools or to obtain supplemental educational services. Finally, the law mandates the fundamental restructuring of any school that fails to improve over an extended period of time.
