The purpose of this paper is to present an overview regarding how several states use a performance or proficiency index in their determination of adequate yearly progress (AYP) under the No Child Left Behind Act of 2001 (NCLB).  Typically, indexes are based on one of two weighting schemes: (1) either they weight academic performance levels-also referred to as student academic achievement levels-or (2) they weight proficiency by student enrollment-those enrolled for a full academic year-across grades in order to adjust for differing Annual Measurement Objectives (AMOs) in a school or district.
