This paper profiles the student subgroup achievement and gap trends in Kentucky for 2010. In grade 8 (the only grade in which subgroup trends were analyzed by achievement level), Kentucky showed mostly gains in both reading and math at the basic, proficient, and advanced levels for racial/ethnic subgroups, low income students, and boys and girls. Gains tended to be greater in math than in reading. Achievement gaps narrowed in both reading and math in grades 4, 8, and high school in most, but not all, cases. Comparable data were available from 2007 through 2009. (Contains 9 tables.)
