Summary:
ZIP code 61606 has two K–4 elementary schools, Whittier Primary School and Franklin Primary School, both in Peoria School District 150. In 2025–2026, both schools improved their all-grades test results, but their results remained below state averages overall; the most important difference for families is that Whittier scored substantially higher than Franklin in both subjects.
Whittier stands out at the top: its all-grades proficiency was 48% in ELA and 36% in math, compared with 33% and 18% at Franklin—gaps of 15 and 18 percentage points. Franklin had the lowest results and was 24 points below the state in ELA and 22 points below in math. Whittier’s fourth-grade ELA result was a bright spot at 60%, 4 points above the state; Franklin’s was 42%, 14 points below. SchoolDigger’s 2025–2026 rankings also favor Whittier: it ranked 1,203 of 1,737, in the 31st percentile with 2 stars, while Franklin ranked 1,592, in the 8th percentile with 0 stars.
Scores rose at both schools from 2024–2025 to 2025–2026, and the average gap with the state narrowed: in ELA, the two-school average rose from 27% to 40%, while the state gained 3 points; in math, the average rose from 20% to 27%, while the state gained 1 point. Gains were uneven: Franklin’s math proficiency increased by only 2 points, compared with 11 points at Whittier. Other measures offer context, not explanations: Whittier’s student-teacher ratio was 13.5:1 versus Franklin’s 12.8:1, and its 2024–2025 free/reduced lunch eligible share was 80% versus 93% at Franklin. Chronic absenteeism ran higher at Whittier—25% versus 22% at Franklin—even though Whittier had stronger test results.
