6 public K-12 schools in Millersville 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, Millersville has more public-school enrollment than 54% of the 4,487 US cities in this directory. Old Mill High enrolls 38.0% of Millersville'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.
A full K–12 ladder sits inside the city boundary
Millersville's list includes 2 elementary, 2 middle, and 1 high-school campus, plus 1 combined-grade record. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
A small portfolio contains radically different campus scales
Millersville lists only 6 schools, yet reported enrollment runs from 128 to 1,832 students, a 14-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.

Old Mill High accounts for 38.0% of all Millersville public-school enrollment
That dominant concentration means Millersville-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.
Millersville school enrollment varies 14× across entities
Millersville school enrollment ranges from 128 students (lowest) to 1,832 students (highest), a spread of 1,704 students. That spread reflects typical urban portfolio variation between specialty programs and large neighbourhood schools. 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.
Millersville operates one school district — a single-district system
Millersville'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.
Millersville student-teacher ratio is 12.7:1 — 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 Millersville
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.
