A high school principal and faculty celebrated after hearing that their students in each of the quartiles had improved in both reading and mathematics on the state accountability assessment. Because of the percent of increases in achievement levels on the test, the Florida Department of Education awarded the school an A for 2011. Shortly thereafter the principal was notified that the school did not make adequate yearly progress (AYP) under the No Child Left Behind Act of 2001 requirements. Each of the seven student subgroups considered for AYP did not meet the established goals. Because the school is large--2,200 students--and the community diverse, the school must meet AYP criteria for all subgroups. When community members and parents heard that their "A" high school did not make AYP they wanted to know why. This article attempts to answer such questions by discussing test results and how NAEP and state tests compare.
