Computation of Confidence Intervals for Growth Performance in Determination of Safe Harbor Eligibility
Mulvenon, Sean W.; Stegman, Charles E.
Journal of Educational Research & Policy Studies, v6 n1 p36-47 Spr 2006
As part of No Child Left Behind (NCLB) legislation, many states are using confidence intervals to determine a range of scores for evaluating a school system. More specifically, the states are employing confidence intervals to help minimize measurement error in determining a school system's performance. The methodology and techniques employed in these NCLB calculations for confidence intervals have raised several questions with regard to appropriateness, methods, and the transfer to educational policy. The purpose of this paper is to review the methodology, application, and impact of the various methods in regard to educational policy. Additionally, simulations that examine variations in sample size and proportions were completed in order to examine how inconsistency can impact the determination of a school's performance relative to the achievement goals.
