Summary

Robert Clow Elementary School serves 343 students in grades K–5 in Naperville, Illinois. Its clearest strength is math compared with district and state results, while its all-grade test scores are around the middle of the nearby-school group.

In 2025–2026, 79% of Clow students were proficient in English language arts (ELA) and 75% in math. Both results were above Indian Prairie CUSD 204 (74% ELA and 63% math) and state rates (56% and 40%). The gaps were 5 and 13 percentage points over the district, and 23 and 36 points over the state. Locally, however, five nearby schools scored higher and five lower than Clow in each subject; nearby averages were 78% in ELA and 72% in math. Fifth-grade science was less distinctive: Clow’s 73% was just 0.2 points above the nearby average, and four schools scored higher. Within Clow, fifth-grade ELA stood out at 91%, second-highest among schools with data, while grade 3 ELA was 65% and grade 4 was 77%.

Scores have risen over the three reported years: ELA increased from 71% in 2023–2024 to 79% in 2025–2026, and math from 62% to 75%. Over that period, Clow’s lead over the state narrowed by 7 points in ELA but widened by 2 points in math. SchoolDigger ranked Clow 151st of 1,737 schools in 2025–2026, at the 91st percentile with five stars; six of the 10 nearby schools had higher percentiles. Clow also had the group’s lowest reported student-teacher ratio, 11.4 in 2024–2025, compared with a nearby average of 14.4. Its free/reduced lunch eligible share was 13% that school year, close to the nearby average of 14%. SchoolDigger’s ranking for Low Socio Economic Status Students rose from the 83rd percentile in 2022–2023 to the 99th in 2023–2024, then stood at the 95th in 2024–2025, indicating a strong latest statewide standing for that group.
