This paper profiles the student subgroup achievement and gap trends in Ohio for 2010. In grade 8 math (the only grade in which subgroup trends were analyzed by achievement level), Ohio showed a clear trend of gains for all major subgroups at the basic-and-above, proficient-and-above, and advanced levels, with one exception. In grade 8 reading, however, declines outnumbered gains. Achievement gaps generally narrowed at grades 4, 8, and 10, although some gaps widened in reading. The periods with comparable data varied by subject and grade level, with trends extending from 2004, 2005, or 2006 through 2009. Ohio did not make available the data needed to calculate gains based on average test scores. (Contains 7 tables.)
