Kingsbury Country Day School

Kingsbury Country Day School is a single private elementary school in Oxford, Michigan, serving grades PK through 8 with 335 students and a favorable 12.8:1 student-teacher ratio. This one-school district means all district and school data are identical, and the school serves a relatively affluent population with only 18.21% of students eligible for free or reduced lunch.

The school shows a striking "V-shaped" performance pattern. Upper grades (6-8) are clear strengths, with 7th grade ELA proficiency at 65.2% (26.8 points above the state average) and 7th grade math at 56.5% (23.2 points above state). Science and social studies are consistent bright spots, with the school outperforming state averages by 15-24 points across all tested grades in both years. However, lower grades (3-5) experienced dramatic declines between 2024-2025 and 2025-2026. Most concerning is 5th grade, where ELA proficiency fell from 66.7% to 32.5% and math plummeted to just 12.5%—nearly 20 points below the state average. Third grade also dropped significantly, with ELA falling from 55.3% to 31.8% and math from 44.7% to 31.8%. This decline in early grades has driven the school's state ranking down from the 83rd percentile (2023-2024) to the 47th percentile (2025-2026), despite upper-grade scores remaining strong.

For parents, this school offers exceptional instruction in middle grades but raises concerns about early elementary education. The math weakness in grades 3-5 is particularly notable given the school's demographic advantages and small class sizes. Chronic absenteeism affects 21.8% of students—better than the state's 27.9% but still high for a school with these resources. The dramatic year-over-year drops suggest a possible cohort effect or curriculum changes rather than systemic failure, as the same students who struggled in 5th grade may rebound in 6th grade, where the school excels. Parents considering this school should ask about math curriculum alignment between grades and how the school plans to address the lower-grade decline, while taking comfort in the proven success of the upper-grade program.
