National city placement

One campus shapes the city average

According to NCES CCD 2024-25, Sudbury has more public-school enrollment than 43% of the 4,487 US cities in this directory. Lincoln-Sudbury Regional High enrolls 36.4% of Sudbury'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 Sudbury'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 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 16-point gap between Lincoln-Sudbury Regional High and Israel Loring School shows the range hidden by Sudbury'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.

Lincoln-Sudbury Regional High accounts for 36.4% of all Sudbury public-school enrollment

That dominant concentration means Sudbury-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.

Sudbury school enrollment varies 3.8× across entities

Sudbury school enrollment ranges from 382 students (lowest) to 1,445 students (highest), a spread of 1,063 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.

Sudbury student-teacher ratio is 13.0:1 — 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.

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.
