This paper profiles the student subgroup achievement and gap trends in Oklahoma for 2010. Oklahoma made progress in narrowing achievement gaps for most major subgroups on the End-of-Instruction (EOI) test in Algebra I. Trends in achievement gaps could not be determined for other grades in math, or for any grades in reading, because the state changed its performance standards in 2009, making it inappropriate to compare current and previous years' test results. For the same reason, subgroup trends by achievement level at grade 8 could not be determined. (Contains 9 tables.)
