Elementary Schools in Flossmoor School District 161

The four elementary schools in Flossmoor School District 161 enroll 1,480 students; three serve kindergarten through grade 5, and Flossmoor Hills Elementary School serves prekindergarten through grade 5. In 2025–2026, the four-school averages were 58% proficient in English language arts (ELA) and 43% in mathematics, slightly above state results of 56% and 40%; fifth-grade science averaged 47%, just below the state’s 48%. The clearest takeaway is that those averages hide a wide divide between the schools’ stronger and weaker results.

Western Avenue Elementary School and Flossmoor Hills stand out: Western led ELA at 70%, while Flossmoor Hills led mathematics at 54%. Both were well above the state in both subjects. At the other end, Heather Hill Elementary School scored 48% in ELA and 38% in mathematics, and Serena Hills Elementary School had the lowest results, at 44% and 29%. Western also led fifth-grade science with 58%, 11 percentage points above the state; the other schools ranged from 37% to 48%.

Recent changes were mixed: the group’s ELA average fell 1 point, while mathematics was nearly unchanged; state averages rose in both, narrowing the schools’ average advantage. Fifth-grade science improved by 14 points on average, nearly catching the state.
