Test scores remained essentially the same between 2006 and 2010 even though 30% more high school students have taken the ACT over this period and the group of students has become more heterogeneous, including more graduates from each racial/ethnic group.
Composite score averages ranged between 21.0 and 21.2 points during this time. The four subject score averages (English, Mathematics, Reading, and Science) showed similar changes in absolute value ranging between 0.1 and 0.2 point depending on the subject area.
