Summary:
Arlington Heights School District 25 has seven elementary schools serving through grade 5, with Ivy Hill and Greenbrier also serving prekindergarten. In 2025–26, the seven-school averages were 76% proficient in ELA, 68% in mathematics, and 74% in grade-5 science, compared with state results of 56%, 40%, and 48%. Results vary considerably across schools, especially in ELA and mathematics. The most important finding is that all seven schools exceed state results in all three reported measures, while Patton leads the group.
Patton stands out in all-grades results, with 86% proficient in ELA and 80% in mathematics; those scores are 12 and 14 percentage points above the other six schools’ averages. SchoolDigger ranks Patton 67th of 1,737 schools, in the 96th percentile, with five stars. Olive-Mary Stitt leads grade-5 science at 82%, about 9 points above the other schools’ average. At the other end, Westgate has the lowest scores in all three comparisons: 63% in ELA, 60% in mathematics, and 70% in science. Even so, those results are above the state by 7, 20, and 22 points, respectively.
Recent trends are mixed: average ELA rose 2 points and grade-5 science rose 7 points from 2024–25 to 2025–26, while mathematics fell 4 points. The school-to-school exceptions may matter when comparing options: Greenbrier’s ELA rose 9 points, but it also had the highest chronic absenteeism rate at 16%, versus 9% districtwide; its ELA and math scores remain above the group averages. Reported student-teacher ratios range from 8.8 at Greenbrier to 14.4 at Ivy Hill, without matching a simple pattern in achievement. All schools report free/reduced lunch eligible figures for 2024–25, ranging from 6% at Stitt to 24% at Ivy Hill; these are context, not an explanation for results. SchoolDigger rankings are a separate indicator, and the number of schools ranked differs by year.
