6 public K-12 schools in Corning 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, Corning has more public-school enrollment than 25% of the 4,487 US cities in this directory. Corning-Painted Post High School enrolls 54.6% of Corning'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 Corning's 6 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 0 middle and 2 high-school records. Families comparing later grades should rely on those individual rows rather than the all-school mean.
A small portfolio contains radically different campus scales
Corning lists only 6 schools, yet reported enrollment runs from 24 to 1,524 students, a 64-fold range. In a portfolio this compact, the smallest record may be a specialized or nonstandard setting rather than a miniature version of the largest campus. That distinction affects how ratios and program fields should be read. Compare similarly configured grade levels first; combining the extremes into one city average conceals more than it explains.

Corning-Painted Post High School accounts for 54.6% of all Corning public-school enrollment
That is an overwhelming concentration, leaving the rest of Corning a distant remainder — means Corning-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. Because it contains a majority of the affected population, enrollment-weighted aggregates will sit closer to this entity's reported fields than to those of smaller peers; an unweighted entity count answers a different question.
Corning school enrollment varies 64× across entities
Corning school enrollment ranges from 24 students (lowest) to 1,524 students (highest), a spread of 1,500 students. That ratio is an extreme outlier spread — among the widest gaps observed anywhere in this dataset. 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.
Corning operates one school district — a single-district system
Corning'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.
Corning student-teacher ratio is 12.3:1 — 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.
Most racially and ethnically mixed schools in Corning
Ranked by the Simpson student-body diversity index (0-100) from NCES race and ethnicity data, where higher means a more evenly mixed student body. It measures mix, not quality.
Which Corning school has the highest Resource Investment Index? ▼
Corning Painted Post High School Learning Center has the highest Resource Investment Index among the Corning schools in this federal-data comparison at 67/100. The index summarizes reported staffing, counseling, gifted-program, and attendance inputs; it is not an academic rating.
How many schools are in Corning, NY? ▼
Corning has 6 public schools with a total enrollment of 2,789 students. Average student-teacher ratio: 12.3:1.
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. See the guide to understanding NCES data.
