Summary

Col. Zadok Magruder High is a mid-sized high school in Rockville, MD, serving 1,671 students in grades 9-12 within the highly rated Montgomery County Public Schools district, and it has shown recent improvement in its state ranking, climbing from the 44th percentile to the 62nd percentile over the past decade.

Magruder presents a unique profile of strengths and challenges that sets it apart from nearby schools. Its most dramatic differentiator is an exceptional performance in English Language Arts (ELA), with a 63% proficiency rate that exceeds both the district (58.5%) and state (51.7%) averages. However, this is paired with an extremely low math proficiency rate of just 1.9%, which is far below the district average of 36.9% and even lower than the lowest-performing nearby school, Rockville High (6.5%). This math crisis appears to be a systemic issue across the region, as even top-ranked Thomas S. Wootton High (8.6%) has low math proficiency, but Magruder is the most extreme example. The school also has a high chronic absenteeism rate of 37.9%, the second-highest among its peers, yet it maintains a strong graduation rate of 90.3%, above the district average of 88.7%.

Magruder sits in the middle of a high-performing neighborhood, outperformed by schools like Thomas S. Wootton High and Sherwood High but ahead of John F. Kennedy High and Gaithersburg High. Its per-student spending of $20,372 is among the highest in the comparison group, yet this investment has not translated into top-tier overall results, particularly in math. A valuable comparison point is Rockville High, which has similar demographics but a significantly higher math proficiency rate (6.5%), suggesting a more effective approach to math instruction that Magruder could study. The data paints a picture of a school with strong ELA instruction but a significant portion of students who are disengaged and struggling in math, raising questions about how resources are allocated to address these pressing challenges.
