This paper profiles the student subgroup achievement and gap trends in Washington for 2010. In grade 8 (the only grade in which subgroup trends were analyzed by achievement level), Washington showed across-the-board gains in math--improvements at the basic, proficient, and advanced levels for all racial/ethnic subgroups, low-income students, and boys and girls. Achievement was mixed, however, for this grade level in reading. Conversely, progress in narrowing achievement gaps was made in reading at grades 4, 8, and 10, however, it was mixed in math. Comparable data were available for 2002-2009 at grades 4 and 10 and for 2006-2009 at grade 8. (Contains 9 tables.)
