Under the No Child Left Behind Act of 2001, how many students are needed in a subgroup for it to count towards AYP?

Under the No Child Left Behind Act (NCLB) of 2001, for a subgroup to count towards Adequate Yearly Progress (AYP), it must consist of at least 30 students. This threshold was established to ensure that subgroups have sufficient numbers to provide reliable data and to prevent the compromising of student privacy. By requiring a minimum of 30 students, the act aimed to allow schools to accurately assess the performance of various subgroups, including racial and ethnic minorities, students with disabilities, and English language learners. This requirement helps to ensure that the educational needs of these subgroups are adequately addressed and that accountability measures are fairly applied.
