How are confidence intervals used in the AYP decisions?
A confidence interval to ensure 99 percent certainty of the school’s or the school district’s AYP classification is calculated around the Annual Measurable Objective (AMO), the annual target for the school or school district. If the school’s or the school district’s index is within the confidence interval, it is determined to have met AYP. On the AYP report, we indicate the lower confidence bound of the AMO. An index that meets this lower bound results in a school or school district meeting AYP.
