Summary:
Cusd 200 includes 19 schools—13 elementary, four middle and two high schools—serving students from elementary through high school in the Wheaton area. In 2025–2026, elementary and middle school averages were above state results in all-grades ELA and math, and both high schools exceeded state results in every listed ACT and PreACT comparison. But school results vary substantially, especially in elementary math, where scores ranged from 51% to 83%; the most important takeaway is that district-wide strength does not mean the experience or results are the same at every school.
Longfellow Elementary School led the elementary schools with 83% in both ELA and math, respectively 27 and 43 points above the state. Among middle schools, Edison Middle School led in ELA at 91% and grade 8 science at 77%; its ELA result was 34 points above the state. Franklin Middle School led middle-school math at 66%. At the lower end, Clifford Johnson School had the lowest elementary ELA and math scores, 62% and 51%. Those results were still 6 and 11 points above state levels, but 17 and 12 points below district levels.
Elementary averages changed little from 2024–2025 to 2025–2026, while state ELA rose 3 points; middle-school averages gained 5 points in ELA and 3 in math. Grade 5 science improved by about 6 points on average, less than the state’s 7-point rise, and individual schools moved in both directions. SchoolDigger percentiles also shifted: Johnson fell from 75 to 60, while Edison rose from 93 to 95; these are rankings, not test-score changes. The reported free/reduced lunch eligible share (SY 2024–2025) ranged from about 10% at Whittier to 63% at Johnson, but schools with similar shares had different results. Ratios also offer no simple guide: Bower Elementary School reported 9.4 students per teacher, while top-performing Longfellow reported 14.4.
