Bannockburn School District 106

Schools in Bannockburn School District 106 consist of one listed school, Bannockburn School, an elementary school serving kindergarten through grade 8 in Bannockburn, with 165 students. With only one school, there is no meaningful local school-to-school comparison. In 2025–2026, the school’s all-grades results were well above Illinois in both ELA—94% versus 56%—and math—82% versus 40%; its advantages were 37 and 42 percentage points, respectively. The most important finding is that its results exceed state averages across both core subjects, not just one.

Bannockburn School is both the highest- and lowest-ranked school locally by default, and its reported grade-level results show strengths across subjects. In ELA, every reported grade was above the state; grade 6 was the school’s lowest at 82%, still 24 points above Illinois. In math, grade 5 was lowest among reported grades at 69%, but remained 33 points above the state. Grade 8 math had the largest reported grade-level lead: 92% compared with 35% statewide, a 58-point advantage. Science results were also higher than state figures: grade 5 scored 75% versus 48%, and grade 8 scored 92% versus 52% in 2025–2026.

Results improved over the two reported years, especially in ELA and grade 8 science. All-grades ELA rose from 87% in 2024–2025 to 94% in 2025–2026, while the state rose from 53% to 56%; the school’s lead widened by 4 points. Math was essentially unchanged, moving from 81.4% to 81.5%, and its already large advantage narrowed by 1 point. Grade 8 science climbed from 75% to 92%, with its state advantage growing by 11 points. SchoolDigger gives the district 5 stars and ranks it 16th of 738; the school’s SchoolDigger rank was at the 97th percentile in 2025–2026. Context figures include a student–teacher ratio of 9 in 2024–2025 and 20% free/reduced lunch eligible in 2021–2022; these describe the school, not the reasons for its results.
