Summary:
ZIP code 61820 has seven schools—four elementary, two middle and one high school—serving grades K–12 in Champaign CUSD 4. Results differ sharply among the elementary schools: the 2025–2026 all-grades ELA scores range from 57% to 17%, and math scores from 64% to 16%. The most important finding for families is that the ZIP code’s school experience varies substantially by school, especially at the elementary level.
South Side Elementary School stands out among elementary schools, leading in ELA, math and fifth-grade science; its scores are 57%, 64% and 58%, respectively. It is slightly above the state in ELA and exceeds the state by 24 percentage points in math and 11 points in science. At the other end, Washington Elementary School scores 17% in ELA, 16% in math and 21% in fifth-grade science—39, 48 and 37 points below the elementary leaders. The middle schools are close in all-grades ELA and math, with Franklin Middle School ahead by about 1 point in each, while Edison Middle School leads eighth-grade science by 12 points. Central High School is above the state in all three 11th-grade ACT subjects.
Recent gains are strongest in elementary science and middle-school ELA: their school averages rose 14 and 8 points, respectively, from 2024–2025 to 2025–2026. Elementary ELA rose only about 1 point on average, and middle-school math edged down. SchoolDigger’s statewide percentile rankings declined for all seven schools from 2023–2024 to 2025–2026; South Side moved from the 73rd to the 67th percentile, while Stratton Elementary School fell from the 22nd to the 4th. Staffing and income figures do not show a simple pattern with scores: for example, Bottenfield Elementary School and Stratton have similar enrollment and student-teacher ratios—14.8 and 14.4—yet very different results. The reported free/reduced lunch eligible measure for school year 2024–2025 was 43% at South Side and 76% at Stratton.
