Summary:
Five elementary schools serve ZIP code 62234, all in Collinsville CUSD 10: three offer PK–4 and two K–4, with enrollment ranging from 113 to 498 students. In 2025–2026, the schools’ average proficiency was 40% in ELA and 33% in math, compared with state results of 56% and 40%; two schools exceeded the state in math, while none did in ELA. The clearest area-wide concern is that ELA results lag the state more broadly and by more: the five-school average was 16 points below the state, versus 6 points below in math.
Summit Elementary School led all-grades ELA at 51%, about 11 points above the group average, and was just behind Webster Elementary School in math: 42.6% versus 42.7%. Both were about 3 points above the state in math. At the other end, Kreitner Elementary School had the lowest all-grades results: 35% in ELA, 22 points below the state, and 23% in math, 16 points below. Grade-level results show different strengths: Summit led grade 3 in ELA and math, at 52% and 57%, while Webster led grade 4 at 53% in ELA and 51% in math. Summit’s grade-4 math result is suppressed, so it cannot be compared.
Recent changes favor neither subject: from 2024–2025 to 2025–2026, the group’s ELA average fell 2 points as the state rose 3, and its math average fell 6 points as the state rose 1. Summit’s ELA improved 4 points, but its math fell 13; Webster’s math slipped just 1 point. SchoolDigger percentile rankings also declined at all five schools between 2023–2024 and 2025–2026, from 32 to 16 at John A Renfro Elementary School, 41 to 10 at Kreitner, 55 to 34 at Webster, 47 to 15 at Twin Echo Elementary School, and 56 to 49 at Summit. Other measures do not sort schools neatly by results: student-teacher ratios ranged from 11.7 at Kreitner to 15.4 at Twin Echo, and all schools reported free/reduced lunch eligible for 2024–2025, from 57% at Summit to 90% at Kreitner. These are useful context for comparing schools, not explanations for achievement.
