5 public K-12 schools in South Glens Falls from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
According to NCES CCD 2024-25, South Glens Falls has more public-school enrollment than 22% of the 4,487 US cities in this directory. South Glens Falls Senior High School enrolls 36.5% of South Glens Falls's public-school students. That is enough concentration for one institution to pull the citywide enrollment, staffing, and Resource Index averages toward its own profile. The smaller campuses below should therefore be compared directly rather than inferred from the headline mean; their grade configurations and program footprints can be materially different even inside the same district.
The school portfolio is elementary-weighted
3 of South Glens Falls's 5 listed schools are elementary campuses. That composition means citywide enrollment and staffing averages are influenced more by early-grade operating patterns than by the city's 1 middle and 1 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
Campus spread matters more than the city mean
The 9-point gap between Moreau Elementary School and Harrison Avenue Elementary School shows the range hidden by South Glens Falls'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.

South Glens Falls Senior High School accounts for 36.5% of all South Glens Falls public-school enrollment
That dominant concentration means South Glens Falls-wide averages can mask substantial variation outside the largest entity. Grade level: High. The share measures enrollment concentration only; it does not establish how districts allocate programs, capital, or staff. Enrollment-weighted aggregates give this entity more weight than any smaller peer, while an unweighted entity average treats every record equally.
South Glens Falls school enrollment varies 3.3× across entities
South Glens Falls school enrollment ranges from 283 students (lowest) to 939 students (highest), a spread of 656 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.
South Glens Falls operates one school district — a single-district system
South Glens Falls's listed schools share one district boundary, budget authority, and reporting chain. That makes citywide and districtwide governance easier to compare, but it does not make individual campuses uniform: grade configuration, staffing, programs, and student need can still vary materially within the same school district.
South Glens Falls student-teacher ratio is 14.5:1 — near the typical range (US average ~15.7) — citywide staffing is neither unusually lean nor unusually crowded by this measure
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 South Glens Falls is typically wider than the South Glens Falls-aggregate figure suggests.
