Summary:
East High School is the only high school listed in the Aurora area of Aurora East Unified School District 131, serving grades 9–12 and enrolling 4,020 students. In 2025–2026, its proficiency results were below the state’s in all nine reported subject-and-grade comparisons, with gaps of 21 to 27 percentage points. The most important takeaway is that this gap appears across grades and subjects, not just in one area.
Because it is the only school listed, East is both the highest- and lowest-ranked school in this group, which is not a meaningful local comparison. Against the state, its closest result was grade 10 PreACT mathematics: 16% proficient versus 36%, a 21-point gap. Its widest gap was grade 11 ACT ELA: 23% versus 50%, or 27 points. Across subjects, mathematics was relatively closest to the state, with an average gap of 23 points; the gaps were 24 points in science and 26 in ELA. Even in math, however, East remained below the state in every reported grade.
Results moved in different directions by grade: all three grade 11 ACT gaps narrowed slightly from 2024–2025 to 2025–2026, while all six PreACT gaps widened. The sharpest setback was grade 10 PreACT science, where East’s proficiency fell 8 points, compared with a 1-point state decline, widening the gap by 7 points. Other measures show a mixed picture: chronic absenteeism was 55%, 31 points above the state, while the dropout rate was 1%, 1 point below it; graduation was 87%, 3 points below the state. For context, in 2024–2025 the school had 18.8 students per teacher, and 64% were free/reduced lunch eligible. These figures describe the school, but the single-school list offers no peer school for families to compare.
