How the Marietta Public-School Landscape Breaks Down
Marietta, GA enrolls 53,133 students across 60 public schools reporting to the National Center for Education Statistics. Of those, 1 are charter schools, giving families genuine alternatives to the traditional neighbourhood assignment model. The average student-teacher ratio across the city is 13.6:1, 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 Marietta is Osborne High School, scoring 44/100 (D) with 2,790 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.
Marietta 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 Marietta housing costs, wage data, and crime statistics — context many parents weigh alongside test-adjacent school signals when relocating.

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.
Marietta student-teacher ratio is 13.6:1 — 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 Marietta is Osborne High School with a quality score of 44/100. There are 60 public schools in Marietta with 53,133 total students.
