7 public K-12 schools in Duncan 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, Duncan has more public-school enrollment than 69% of the 4,487 US cities in this directory. Duncan's 7 listed schools all sit inside one district, creating a compact governance structure with one budget, board, and reporting chain. That makes citywide comparisons cleaner than in places split across several districts, but it does not make the campuses interchangeable: elementary, middle, and high-school staffing needs differ. The ranked list is best read as variation inside one system rather than competition among separate local authorities.
A full K–12 ladder sits inside the city boundary
Duncan's list includes 2 elementary, 1 middle, and 2 high-school campuses, plus 2 combined-grade records. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
One district, but meaningful resource variation
Duncan's schools share one district authority while their average Resource Investment Index ranks at the 75th percentile among listed cities. Shared governance removes one source of policy variation, but it does not erase campus differences by grade span or enrollment. The 18-point gap between Beech Springs Intermediate and James Byrnes Freshman Academy measures the remaining local spread. Use the district-level picture for common budget context, then compare the school components to see whether staffing, counseling, gifted-program reporting, or attendance accounts for each campus's position.

James F. Byrnes High accounts for 34.5% of all Duncan public-school enrollment
That dominant concentration means Duncan-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.
Duncan school enrollment varies 4.1× across entities
Duncan school enrollment ranges from 584 students (lowest) to 2,391 students (highest), a spread of 1,807 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.
The reported share clears the 50% majority mark. Title I operates under the Every Student Succeeds Act (ESSA, 2015), but its statutory allocation uses additional LEA-level counts and rules not represented by this average. This percentage is an economic-need context measure; it does not establish a Title I award, show dollars received, or describe how funds are distributed among campuses.
Duncan operates one school district — a single-district system
Duncan'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.
Duncan student-teacher ratio is 14.7:1 — 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 Duncan is typically wider than the Duncan-aggregate figure suggests.
Most racially and ethnically mixed schools in Duncan
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.
