16 public K-12 schools in Del Rio from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
National city placement
According to NCES CCD 2024-25, Del Rio has more public-school enrollment than 80% of the 4,487 US cities in this directory. Del Rio's average Resource Investment Index falls in the lower portion of the 4,487-city comparison set. The index is a resource snapshot, not an academic grade: it reflects the federal staffing, counselor, gifted-program, and attendance fields available for local campuses. The most useful next step is to open the individual schools below and identify which component is pulling each score down, because the same city average can hide very different campus-level constraints.
Del Rio's list includes 6 elementary, 2 middle, and 4 high-school campuses, plus 4 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.
The 34-point gap between Heritage Academy of Del Rio Middle and Irene C Cardwell El shows the range hidden by Del Rio'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.
That concentration means Del Rio-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.

Del Rio school enrollment ranges from 60 students (lowest) to 2,447 students (highest), a spread of 2,387 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.

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 Del Rio is typically wider than the Del Rio-aggregate figure suggests.
19% 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. Open each school record to compare enrollment and staffing directly.

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.
