29 public K-12 schools in Alpharetta from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
National city placement
According to NCES CCD 2024-25, Alpharetta has more public-school enrollment than 96% of the 4,487 US cities in this directory. Alpharetta sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
15 of Alpharetta's 29 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
The 18-point gap between Haynes Bridge Middle School and Medlock Bridge Elementary School shows the range hidden by Alpharetta's average Resource Investment Index. The city figure is useful for national placement, but families ultimately choose among campuses with different grade spans, enrollment, district affiliations, and reported support fields. Start with schools serving the relevant grade level, then compare the index components rather than assuming the city average describes any one classroom.
Alpharetta school enrollment ranges from 498 students (lowest) to 2,527 students (highest), a spread of 2,029 students. That relatively narrow ratio reflects an unusually homogeneous school portfolio for a city this size. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.

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 Variation between sub-units within Alpharetta is typically wider than the Alpharetta-aggregate figure suggests.

Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio, counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes: verify current enrollment, attendance boundaries, and programs with the school district before acting.
