Summary

Windsor Knolls Middle in Ijamsville, MD, is a high-performing school within the Frederick County Public Schools district, serving 812 students in grades 6 through 8 with a consistent track record of academic excellence and a low chronic absenteeism rate of just 9.7%.

What truly sets Windsor Knolls apart is its exceptional performance in advanced mathematics. In the 2025-2026 school year, a remarkable 90.5% of students taking Algebra I and 96% of students taking Geometry scored proficient or higher—dramatically exceeding district averages of 33.5% and 59.9%, respectively. This indicates a highly effective program for accelerating students into high school-level math. The school also stands out for its efficiency, achieving top-tier results while spending $14,731 per student, which is notably lower than nearby schools like Crestwood Middle ($17,429) and Ballenger Creek Middle ($16,705). Windsor Knolls is part of a "cluster of excellence" in Ijamsville, alongside Urbana Middle (99th percentile) and Oakdale Middle (93rd percentile), forming a powerhouse of academic achievement in the area.

While Windsor Knolls excels overall, it shares a common challenge with nearby schools: an 8th-grade math proficiency drop to 20.3%, which is typical as advanced students accelerate into Algebra I or Geometry. The school also shows strong support for students from low socio-economic status backgrounds, ranking in the 89th percentile statewide for this group, though it has room for growth with Special Education students (45th percentile). Notably, Windsor Knolls has demonstrated resilience post-pandemic, with its chronic absenteeism rate recovering from a spike of 17.2% in 2021-2022 to just 9.7% for two consecutive years—a faster recovery than peers like New Market Middle (16.3%) and Ballenger Creek (21.4%).
