Adequate Yearly Progress (AYP)
A now-obsolete federal accountability measure under No Child Left Behind that required schools to meet annual proficiency targets or face escalating consequences, replaced by state-designed systems under ESSA.
How It Works
Adequate Yearly Progress was the centerpiece of the No Child Left Behind Act (NCLB) of 2001, which set the ambitious goal of having 100% of students proficient in reading and math by 2014. Each state set annual proficiency targets that increased in a staircase pattern toward 100%, and schools that failed to meet these targets for two or more consecutive years faced escalating consequences: supplemental tutoring, public school choice, corrective action, restructuring, or state takeover. AYP was calculated separately for each student subgroup (racial/ethnic groups, students with disabilities, English Learners, economically disadvantaged students), so a school could fail AYP if even one subgroup missed its target, even if overall performance was strong. This subgroup accountability was AYP's most important innovation, forcing schools to address achievement gaps rather than hiding low-performing students behind high averages. However, AYP was widely criticized for its rigid structure, unrealistic 100% proficiency target, focus on proficiency levels rather than growth, and blunt consequences that stigmatized schools serving challenging populations. By 2014, virtually every school in America would have "failed" under the original targets. The Every Student Succeeds Act (ESSA) of 2015 replaced AYP with state-designed accountability systems that incorporate multiple measures, including growth, and give states more flexibility in setting goals and consequences. OpenSchoolData takes a different approach from AYP by presenting real federal data directly rather than applying pass/fail labels, letting parents interpret the numbers in context.
