How the Gaithersburg Public-School Landscape Breaks Down
Gaithersburg, MD enrolls 20,676 students across 29 public schools reporting to the National Center for Education Statistics. The average student-teacher ratio across the city is 12.8:1, Schools must report at least five campuses in a city to appear in this listing, which is why very small towns may redirect to the broader county or state view.
The highest-ranked campus in Gaithersburg is Gaithersburg High, scoring 56/100 (C) with 2,441 enrolled students at the high level. Families should treat any single ranking as a starting point rather than a verdict — a school serving fewer at-risk students or offering more AP classes will score higher on resource-based composites even if individual teachers or programs elsewhere are stronger. The quality score framework is transparent and rebuilt from raw NCES and Civil Rights Data Collection (CRDC) inputs, so each component can be inspected on the individual school pages linked in the table below.
Gaithersburg schools sit within multiple district boundaries, which matters for property taxes, redistricting votes, and bond measures. Each district files its own NCES F-33 financial return, meaning per-pupil spending can vary noticeably even between neighbouring campuses in the same city. Use the table to sort by enrollment, level, or district, then click any school name for campus-level demographics, Title I status, counselor and nurse staffing, AP courses, chronic-absenteeism rates, and district per-pupil spending. The sidebar links also connect Gaithersburg housing costs, wage data, and crime statistics — context many parents weigh alongside test-adjacent school signals when relocating.
Gaithersburg school enrollment varies 8.8× across entities
Gaithersburg school enrollment ranges from 276 students (lowest) to 2,441 students (highest), a spread of 2,165 students. That relatively narrow ratio reflects an unusually homogeneous school portfolio for a city this size. Per-school staffing, programme depth, and capital-renovation cycles often diverge inside the same city based on enrollment shape — a 200-student magnet runs a different operational model than a 2,000-student comprehensive high school.
Gaithersburg operates only 1 school district — among the most consolidated governance structures in the country
Most Gaithersburg school districts are a single unified district covering the whole city — a structural feature that simplifies inter-school comparison but concentrates policy authority. Consolidation produces narrower variance because resources pool across larger populations, but it can also mask intra-school district inequities — sub-school district differences within a single school district are not visible at this aggregation level. Consolidated systems typically rely more heavily on top-down funding formulas than on local revenue variability.
Gaithersburg student-teacher ratio is 12.8:1 — low (typically associated with smaller schools or per-school staffing investment that often correlates with stronger per-student supports)
student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment — push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
The top-rated school in Gaithersburg is Gaithersburg High with a quality score of 56/100. There are 29 public schools in Gaithersburg with 20,676 total students.
