This paper profiles the student subgroup achievement and gap trends in Wyoming for 2010. Wyoming's demographic profile is such that achievement trends could only be determined for white, Latino, male and female, and low-income student subgroups. In grade 8 (the only grade in which subgroup trends were analyzed by achievement level), the white, Latino, low- income, male and female subgroups made progress at the basic-and-above, proficient-and-above, and advanced levels in math but showed some declines at the advanced level for these groups in reading. Progress was made in narrowing achievement gaps between most subgroups. Comparable data were available for 2006-2009. (Contains 9 tables.)
