Summary

Clifford Johnson School is a K–5 school in Warrenville, Illinois, serving 473 students in Cusd 200. In 2025–2026, its proficiency rates were above Illinois averages in ELA, math and fifth-grade science. The key comparison for families is that the school’s scores were still well below district averages, particularly in ELA and math.

Among nearby K–5 schools, Clifford’s strongest comparison was fifth-grade science: 54% were proficient, compared with a nearby-school average of 49%, a 6-point advantage. ELA was also above the nearby average—62% versus 60%—while math was slightly below it at 51% versus 53%; overall, Clifford was around the middle in ELA and lower in math. Compared with the state, Clifford was ahead by 6 points in ELA, 11 in math and 7 in science. Compared with its district, it trailed by 17 points in ELA, 12 in math and 9 in science. Fifth-grade math is a particular concern within the school: proficiency fell to 44%, down 11 points from third grade, and was 22 points below the state.

Scores have improved since 2023–2024: ELA rose from 47% to 62% and math from 39% to 51%, even as SchoolDigger’s statewide ranking fell from percentile 75 to 60. In 2025–2026, SchoolDigger gave Clifford 3 stars; the district ranked at percentile 88 with 4 stars. Context includes an 11.0 student-teacher ratio in 2024–2025, the second-lowest among nearby K–5 schools, and 63% of students eligible for free/reduced lunch in 2024–2025, the second-highest share among those schools. One subgroup result merits attention: SchoolDigger’s statewide ranking for how well the school serves English Language Learner students was percentile 37, compared with 60 overall, after falling 32 points over two years.
