Summary

Stone Mill Elementary in North Potomac, MD, is a high-performing school within the Montgomery County Public Schools district, serving 516 students from Pre-K through 5th grade in a relatively affluent community where about 14% of students qualify for free and reduced lunch. This school has been a 5-star institution for over a decade, consistently ranking in the top 10-15% of all elementary schools in Maryland, and it maintains a healthy student-teacher ratio of 14.5:1.

What truly sets Stone Mill apart is its exceptional performance with specific student groups, ranking in the 98th percentile for both African American and Special Education students, and the 94th percentile for English Language Learners—a rare achievement that outperforms many high-achieving peers. However, the school has experienced a slight decline in its statewide rank, dropping from 7th in 2015-2016 to a projected 72nd for 2025-2026, while nearby schools like Cold Spring Elementary (ranked 1st) and Travilah Elementary (ranked 13th) have maintained top-tier positions. Stone Mill sits in the middle of a polarized neighborhood, with elite schools like Cold Spring on one end and schools facing more challenges, such as Summit Hall Elementary (ranked 780th) and Fields Road Elementary (ranked 308th), on the other.

One notable pattern is a "5th grade slump" in math, where proficiency drops to 60% compared to 76.9% in 3rd grade and 74% in 4th grade—a decline more pronounced than at Cold Spring (86.5%) or Fallsmead Elementary (68%). On the positive side, Stone Mill boasts remarkably low chronic absenteeism, consistently below 12.5% and as low as 7.4% in 2019-2020, compared to the district average of 22.6% and rates at nearby schools like Rosemont Elementary (29.4%) and Summit Hall (25.9%). The school's per-student spending of $20,312 is above the district average but lower than at higher-needs schools like DuFief Elementary ($31,430), suggesting efficient use of resources to achieve strong results.
