Recent results show both gains and setbacks. The Grade School’s ELA lead narrowed from 9 percentage points in 2024–25 to 7 in 2025–26, and its math lead narrowed from 7 to 3 points. At the High School, Grade 11 ACT math fell 14 points year over year, while Grade 9 PreACT ELA fell 10 points; by contrast, Grade 10 PreACT math rose 8 points and Grade 9 science rose 8. SchoolDigger’s percentile rankings also fell, from 71 to 52 at the Grade School and from 65 to 55 at the High School. In 2024–25, free/reduced lunch eligibility was 62% at the Grade School and 51% at the High School; student-teacher ratios were 12:1 and 10.8:1. These are contextual differences, not explanations for results, and the schools’ different grade spans mean their scores are not a like-for-like ranking.
