Christopher Elementary stands out in ELA, exceeding state proficiency in every reported grade; its strongest grade-level advantage was 21 points in grade 6, while grade 7 was just above the state. Math is the main concern: the school was above the state only in grade 3, at 59% versus 49%, and below in grades 4–7. At Christopher High, grade 9 PreACT ELA was a bright spot at 66%, 5 points above the state, but grade 10 ELA and science were 20 and 22 points below. Grade 11 ACT results were also below state levels by 4 points in ELA, 4 in math, and 9 in science. Because the schools serve different grades and take different assessments, their test results are not a direct school-to-school comparison.
Results have improved in several areas, though not across the board: from 2024–2025 to 2025–2026, elementary all-grades ELA rose 13 points and math 11, while high school ACT proficiency increased 13 points in ELA, 25 in math, and 14 in science. SchoolDigger percentiles also rose from 2023–2024 to 2025–2026, from 39 to 52 for elementary and 28 to 34 for high school. For context, in 2024–2025, free/reduced lunch eligible students were 61% at elementary and 59% at high school; student-teacher ratios were 13.9 and 10.8, respectively. Attendance differs too: elementary chronic absenteeism was 18%, below the state’s 24%, while high school was 29%; high school graduation was 83%, compared with 90% statewide.
