Summary:
Schools in 62203 include two East St. Louis School District 189 schools serving grades PK–8: Katie Harper-Wright Elementary (PK–4) and Mason/Clark Middle School (5–8), with 958 students combined. The schools serve different grade spans, so their overall scores are not a like-for-like comparison. The clearest shared finding is that every reported grade-specific result is below its same-grade state benchmark, by 24 to 48 percentage points.
In the grade-matched results, Katie Harper-Wright’s grade 4 ELA is the strongest relative result: 32% proficient, compared with 56% statewide, a 24-point gap. Mason/Clark’s grade 7 ELA is the weakest: 10% compared with 58% statewide, a 48-point gap. In reported all-grades results, Katie also scores higher than Mason/Clark by 4 points in ELA (23% versus 20%) and 9 points in math (16% versus 7%); because the schools serve different grades, those figures do not show which performs better at the same grade. SchoolDigger ranks both near the bottom statewide in 2025–2026: Mason/Clark is in the 1st percentile and Katie Harper-Wright in the 2nd.
Recent changes are mixed: reported all-grades ELA scores rose by 4 points at Mason/Clark and 2 at Katie Harper-Wright, while math rose by 3 points at Mason/Clark and fell by 1 at Katie. Mason/Clark’s science also improved in grades 5 and 8, by 4 and 7 points, respectively, though its grade 5 gap to the state widened. SchoolDigger’s historical percentiles declined for both schools: Mason/Clark went from the 8th percentile in 2023–2024 to the 1st in 2025–2026, while Katie went from the 14th to the 2nd. Mason/Clark reports an 11.4 student–teacher ratio and Katie a 13.4 ratio; both report Community Eligibility—all students receive free meals—for 2024–2025. Chronic absenteeism in 2025–2026 was 54% at Mason/Clark and 43% at Katie, compared with 24% statewide.
