The purpose of this study is to investigate the progress being made to close the current achievement gap in Kentucky. Guiding the study is the following research question: Which districts are closing racial and socioeconomic achievement gaps at rates that exceed expectations? The authors assess districts' progress in closing racial and socioeconomic achievement gaps in school year 2017-2018 by employing a growth measure--specifically, a residual gain model--to estimate districts' expected achievement gaps from prior years' achievement gaps. The brief begins with a description of the primary findings of the analysis and next steps for research. It closes with an overview of the study's methodology.
