15 public K-12 schools in Duncanville 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, Duncanville has more public-school enrollment than 82% of the 4,487 US cities in this directory. Duncanville sits near the top of the national city distribution by public-school enrollment, while Duncanville H S alone enrolls 40.6% of local students. The city total therefore does not describe a uniform market: one large campus materially shapes the aggregate, and the remaining schools operate at a different scale. Read the ranked table alongside each campus profile rather than treating the city mean as a typical school.
Combined-grade campuses shape the local portfolio
8 of Duncanville's 15 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.
Campus spread matters more than the city mean
The 31-point gap between Mary E Smithey Pace H S and William Lee Hastings El shows the range hidden by Duncanville'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.

Duncanville H S accounts for 40.6% of all Duncanville public-school enrollment
That dominant concentration means Duncanville-wide averages can mask substantial variation outside the largest entity. Grade level: Combined. 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.
Duncanville school enrollment varies 58× across entities
Duncanville school enrollment ranges from 76 students (lowest) to 4,399 students (highest), a spread of 4,323 students. That ratio is among the widest observed and reflects extreme heterogeneity inside a single city, with small specialty programs listed alongside large comprehensive campuses. 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 sits between 62.5% and 75%, above a simple majority but below the highest descriptive band used here. 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.
Duncanville student-teacher ratio is 15.0:1 — 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 Duncanville is typically wider than the Duncanville-aggregate figure suggests.
13% 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 Duncanville
