These numbers are the public school students in grade 9, 10 or 11 who took the Iowa Statewide Assessment of Student Progress (or the Dynamic Learning Maps alternate test) at their school. Iowa leaves out English learners in their first or second year in U.S. schools, and groups of fewer than 10 students. Iowa publishes how many students in each group were proficient; how they split between Proficient and Advanced is estimated from each group's average score.
