Summary

Greenbrier Elementary is a small, rural school in Boonsboro, MD, serving 259 students from Pre-K through 5th grade as part of Washington County Public Schools. This school stands out for its consistent strength in mathematics, where 37% of students were proficient in the most recent school year—a rate 27% higher than the district average and 36% higher than the state average. This is a notable contrast to nearby schools like Pangborn Elementary (21.1% proficient) and Bester Elementary (13.6% proficient), which struggle more in this subject. Greenbrier also boasts a low chronic absenteeism rate of 17.7%, which is 39% lower than the district average of 29.0%, suggesting a strong culture of attendance and family engagement compared to peers like Ruth Ann Monroe Primary (31.8%) and Eastern Elementary (30.3%).

Greenbrier occupies a unique middle ground in the local school landscape. It is outperformed by nearby Frederick County schools like Myersville Elementary and Wolfsville Elementary (both 5-star schools) and its local peer Boonsboro Elementary (4-star, 88th percentile). However, it significantly outperforms several Washington County schools like Bester, Pangborn, and Eastern, which are ranked in the bottom half of the state. This positions Greenbrier as a stable, above-average option in a region with wide disparities in school performance. An interesting data point is the school's 4th-grade math performance, where 50% of students were proficient—43% higher than the district average—suggesting a particularly effective teacher or instructional strategy in that grade.

While Greenbrier has been a historically strong school, its state ranking has slipped from the 83rd percentile in 2017-2018 to the 64th percentile in 2025-2026, with math proficiency dropping from 43.5% to 37% and English Language Arts from 65.7% to 52.1% over the same period. This warrants attention to see if it's a temporary fluctuation or a longer-term trend. On a positive note, Greenbrier spends $16,091 per student, which is lower than many lower-performing peers like Bester Elementary ($22,906 per student), indicating efficient resource management. The school's performance for its majority demographic group is a concern, ranking in the 24th percentile, which would require deeper investigation into curriculum and support systems.
