Summary

Oswego East High School serves 2,758 students in grades 9–12 in suburban Oswego and is part of CUSD 308. SchoolDigger places it at the 85th statewide percentile and awards it four stars, compared with the district’s 57th percentile and three stars. The clearest headline is strong overall performance, capped by a 97% graduation rate in 2025–2026—7 points above the state and 1 point above the district.

Results are above state and district levels, but the school is not at the top of its nearby group. In 2025–2026 grade 11 ACT results, it ranked fourth among eight schools in each subject: 60% were proficient in ELA, 52% in math and 59% in science. Those results exceeded state rates by 10, 12 and 11 points, and district rates by 3, 4 and 2 points, respectively. ELA is the clearest local strength: the school ranked second in grade 9 and third in grade 10 among the eight schools. Math ranked fourth in both grades, making it a comparatively weaker subject locally, even though its results were above state and district levels.

Recent results are mixed: grade 10 PreACT proficiency rose 6 points in ELA and 5 points in math from the prior year, while grade 11 ACT ELA fell 3 points; these comparisons use the same exam and grade across years. SchoolDigger’s overall percentile rose from 63 in 2015–2016 to 85 in 2025–2026, though it has stayed between 82 and 86 in the four latest years. Its student-teacher ratio is 15.6, below the other nearby schools’ 16.4 average. In 2024–2025, 24% of students were free/reduced lunch eligible, compared with a 35% average among the other seven schools. Two group-specific SchoolDigger measures merit attention: its statewide measure of how well it serves students with disabilities was at the 27th percentile, down from the 83rd the prior year; its measure for multiracial students was at the 36th percentile, after ranking at the 73rd percentile in each of the two prior years. These are group-specific rankings, not percentages of students.

Open Quote This is a very trashy school. The students are so mean, the teachers care somewhat, and the classrooms are full of trash. The district is doing budget cuts to things we love dearly. The students are disrespectful, rude, bitchy, etc. Some education is fine. The school has rats it's that disgusting! Close Quote
