The measurement used for No Child Left Behind (NCLB) are Annual Measureable Objectives (AMOs). AMOs “set the bar” for school performance by groups of students. Targets are set for student performance on the state standardized tests in reading and mathematics as well as for what is termed “Other Academic Indicators (OAI).”
Attendance is deemed an OAI by NCLB for those schools that do not contain a grade 12 that graduates seniors. Progress is considered to be at least a 0.1 percentage point increase up to the 90% threshold. Any fluctuations above the threshold for the attendance will meet the requirement for progress. (There are special conditions that may apply when either of the grade spans, K-8 or 9-12, has fewer than 40 students.)
