Original Research by School Decision on Bannockburn School

Bannockburn School is a small K–8 building in an affluent, carefully preserved residential community of large wooded estates and quiet roads in Lake County, just north of Deerfield. The school serves a tightly bounded population of roughly a hundred and seventy students across its grade span, with an enrollment roughly split between white students and a substantial Asian population, along with smaller shares of multiracial, Black, and Hispanic students. Free-or-reduced-price lunch data was not available for the school; housing values in the area are high, and the village itself is restricted to large single-family homes on large lots with no multifamily housing allowed, which shapes the socioeconomic profile of the student body.

The school's academic results show overall strength in reading and mathematics, with wide variation by grade. In English language arts, Grade 4 stands out with very high proficiency; Grades 6 and 7 also perform well. Grades 3, 5, 7, and 8 show solid proficiency in ELA as well. Math proficiency is more uneven. Grade 3 posts perfect proficiency, while Grade 7 shows strength. Grades 4, 5, 6, and 8 cluster in the mid-to-high range but notably lower than the very best performers. Science, tested in Grades 5 and 8, shows Grade 8 holding steady while Grade 5 lags meaningfully behind both its ELA and math counterparts at the same level. When averaged across all tested subjects and grades, the school's proficiency index places it in the top quartile among Lake County districts, a genuine strength in academic attainment.

Participation rates are uniformly high across subjects and grades, and test participation runs above the regional norm, which means these results are built on near-universal student engagement with the assessments.

The school sits within District 106, which serves Bannockburn alone. No recent parent-relevant changes—such as referendums, levy shifts, or curriculum overhauls—were found in the last several years; the district brief notes only older capital work outside the current window of attention. This suggests a stable, low-turnover operational environment.

Bannockburn is a place where growth is constrained by village zoning designed to preserve a country-estate character. New residential construction is sparse and custom-built, not developer-driven, and the village hosts corporate offices and business parks despite its small footprint, anchoring employment for some residents. Civic life centers on the school campus, the village open space, and equestrian and pedestrian trails within the residential sections. After eighth grade, students feed into Deerfield High School in the adjacent community.

For families in this community, Bannockburn School offers a small, academically solid peer group with above-average standardized performance, particularly in reading. The school's size and setting reflect a deliberate village identity—low-density, family-oriented, with limited diversity by design of the housing stock. Math proficiency varies by grade, and science results at the fifth-grade level warrant a closer look with the school if that grade-to-grade progression concerns you. The housing market is expensive and tightly controlled, making residency itself the primary filter for enrollment; this is not a choice school within a larger district landscape but the singular neighborhood school for the village.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
