Summary
Elmwood Elementary School serves grades K–5 and enrolls 726 students in Naperville, in the highly ranked Naperville CUSD 203. Its 2025–26 proficiency results are well above Illinois averages, but trail the district and most nearby schools; grade 5 Mathematics is its clearest academic weakness.
Compared with the state, Elmwood is ahead in every reported subject: proficiency is 75% in ELA, 65% in Mathematics, and 65% in grade 5 Science, versus state rates of 56%, 40%, and 48%. But the district leads Elmwood by 7 points in ELA, 6 in Mathematics, and 10 in Science. Among nearby K–5 schools, Elmwood’s ELA result is 7 points below the peer average, and its Mathematics result is 12 points below it—the lowest reported result in the group. Grade 5 is especially concerning: Mathematics proficiency is 56%, 13 points below the district and the lowest among nearby schools with grade 5 results; grade 5 ELA is 75%, below all nine nearby peers. SchoolDigger’s subgroup rankings also show a notable gap: in 2024–25, Elmwood ranked at the 24th percentile for Asian students, compared with the 90th percentile overall. For Special Education Students, its ranking fell from the 85th percentile in 2024–25 to the 17th in 2025–26, versus 85th overall; the latest comparison covers just 201 schools, so interpret that shift cautiously.
Results have improved over the longer term, although recent trends are mixed: ELA rose from 62% in 2023–24 to 75% in 2025–26, while Mathematics rose from 53% to 65% overall but fell from 68% in 2024–25. Science slipped from 66% to 65% between 2024–25 and 2025–26. SchoolDigger ranks Elmwood 267th of 1,737 Illinois schools, at the 85th percentile with 4 stars; seven of the 10 nearby schools rank higher by percentile. In 2024–25, its student–teacher ratio was 15.1, compared with a nearby-school average of 13.9. The share of students eligible for free/reduced lunch was 14% that year, close to the nearby-school average of 14%.
