Summary:
Arbor Park School District 145 has four listed schools—three elementary schools and one middle school—with supplied test results covering grades 3–8 at two schools. Only two schools have test scores, and their All Grades results are not a grade-matched comparison because they serve different grades. The clearest concern in the latest results is mathematics: the two schools’ unweighted average was 33% proficient, 6 percentage points below the state average of 40%; their average ELA result was 53%, 4 points below the state’s 56%.
Neither tested school leads across both subjects. In 2025–2026, Arbor Park Middle School had the higher All Grades ELA result, 55% versus 50% at Scarlet Oak Elementary School, a 5-point difference; Scarlet Oak led in mathematics, 36% versus 31%, a 6-point difference. Grade results show notable highs and lows: Arbor Park Middle’s 6th-grade ELA was 8 points above the state, while its 8th-grade mathematics was 13 points below. Scarlet Oak’s 3rd-grade ELA was 7 points above the state, but its 3rd-grade mathematics was 12 points below. SchoolDigger placed Arbor Park Middle at the 39th percentile and Scarlet Oak at the 34th percentile in 2025–2026.
ELA improved at both schools from 2024–2025 to 2025–2026: by 6 percentage points at Arbor Park Middle and 10 at Scarlet Oak, while the state rose 3 points. Mathematics moved differently: Arbor Park Middle gained 2 points, while Scarlet Oak fell by 1; the state gained 1 point. SchoolDigger’s percentile rankings declined over the three supplied years, from 55 to 39 for Arbor Park Middle and from 54 to 34 for Scarlet Oak. As context, in 2024–2025 free/reduced lunch eligible students made up 49% at Arbor Park Middle and 58% at Scarlet Oak; student-teacher ratios were 11.3 and 13.1, respectively. These figures describe different school contexts, not causes of score differences.
