6 public K-12 schools in Frederick 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, Frederick has more public-school enrollment than 40% of the 4,487 US cities in this directory. Frederick Senior High School enrolls 39.6% of Frederick'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.
Combined-grade campuses shape the local portfolio
5 of Frederick's 6 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 composite and staffing measures point in different directions
Frederick's average Resource Investment Index sits at the 67th percentile, while its teacher-staffing measure sits at the 18th percentile. The 49-point percentile gap is a reminder that the index is not a class-size score: counselors, gifted-program reporting, and attendance also affect it. Compare those components directly when two schools have similar index totals; the same headline score can arise from a different mix of reported resources.

Frederick Senior High School accounts for 39.6% of all Frederick public-school enrollment
That dominant concentration means Frederick-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.
Frederick school enrollment varies 6.1× across entities
Frederick school enrollment ranges from 245 students (lowest) to 1,491 students (highest), a spread of 1,246 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.
Frederick operates one school district — a single-district system
Frederick'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.
Frederick student-teacher ratio is 19.4:1 — high (typically associated with larger urban scale or staffing constraints that have widened the headcount gap)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
17% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses.

Most racially and ethnically mixed schools in Frederick
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.

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.
