Prospect Heights School District 23

Prospect Heights School District 23 has four schools—three elementary and one middle—serving prekindergarten through grade 8, with 1,476 students in all. The supplied 2025–2026 test results cover Betsy Ross Elementary School, Anne Sullivan Elementary School and MacArthur Middle School; no current test scores are supplied for Dwight D. Eisenhower Elementary School. The strongest overall takeaway is that every reported grade at the three tested schools is above the state in both English language arts (ELA) and math, with advantages of 11 to 21 points in ELA and 11 to 34 points in math.

MacArthur has the highest reported all-grades ELA result, at 77%, compared with 72% at Anne Sullivan and 59% at Betsy Ross; the spread from highest to lowest is 18 points. In math, Betsy Ross leads at 67%, ahead of MacArthur at 63% and Anne Sullivan at 54%, a 13-point spread. These all-grades comparisons show different strengths across schools, but the grade spans differ. MacArthur’s sixth-grade math result is a notable high point at 70%, 34 points above the state; Anne Sullivan’s fifth-grade science is the smallest reported state advantage, at 7 points.

Recent changes are mixed: the three-school average rose 2 points in ELA, from 67% to 69%, while the state rose 3 points; in math, the average slipped by less than a point, from 62% to 61%, while the state gained 1 point. Anne Sullivan’s fifth-grade science result fell 11 points year over year, though it remained above the state. SchoolDigger rates the district four stars and ranks it 158th of 738 districts, in the 79th percentile. Among the tested schools, student-teacher ratios range from 13.1 to 15.7, and free/reduced lunch eligible shares range from 37% to 42% in school year 2024–2025; these figures provide context, not an explanation for score differences. At MacArthur, for example, sixth-grade math is 20 points higher than eighth-grade math, showing why grade-specific results can matter alongside a school’s overall profile.
