Summary:
Zip code 60115 has one high school, DeKalb High School, serving grades 9–12 with 2,134 students. The most important finding for families is that the school’s reported test results were below state results in every subject and grade in 2025–2026.
There is no local top or bottom school to compare because DeKalb High School is the only high school in the list. Within its results, ELA was the strongest subject relative to the state, while science had the largest average shortfall: across the three grade/test results for each subject, ELA averaged 43% proficient versus 55% statewide, math 27% versus 39%, and science 33% versus 48%. Across all nine results, the school averaged 35% proficient compared with 47% statewide. Science also had two of the largest individual gaps: about 17 points below the state in grade-11 ACT and grade-9 PreACT Secure results.
Results improved modestly overall, but grade-9 science moved sharply in the wrong direction. The school’s nine-result average rose by 1 point from 2024–2025 to 2025–2026, and its average gap from the state narrowed by 1 point; grade-10 science improved by 10 points, while grade-9 science fell by 10 points and its state gap widened by 7 points. SchoolDigger places the school at the 25th percentile, with one star and a rank of 466 out of 620; its percentile declined from 44 in 2023–2024 to 31 in 2024–2025. Graduation was 83% versus 90% statewide, while chronic absenteeism was 34% versus 24%. Context figures include a 15:1 student-teacher ratio in 2024–2025 and 61% free/reduced lunch eligible in 2024–2025. Because only one school is listed, these figures cannot show how it compares with other local schools.
