16 public K-12 schools in Rio Grande City 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, Rio Grande City has more public-school enrollment than 81% of the 4,487 US cities in this directory. Rio Grande City sits in the broad middle of the national city distribution rather than at a single obvious extreme. Its scale, average Resource Investment Index, and staffing position need to be read together: a middle placement on one measure does not cancel a stronger or weaker result on another. The percentile panel makes those dimensions explicit, and the school table shows where the city aggregate breaks into materially different campus profiles.
Combined-grade campuses shape the local portfolio
10 of Rio Grande City's 16 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.
Economic need crosses separate district systems
87.1% of enrollment in reporting Rio Grande City schools is eligible for free lunch, while the city list spans 3 districts. That pairing makes a citywide average especially easy to misread: the need measure follows students, but staffing decisions, calendars, program rules, and federal allocations are administered through separate district structures. The 47-point gap between Veterans Middle and Idea Rio Grande City Academy shows how much reported resource capacity can vary inside the same municipal label. Compare schools within the same district first, then use the city view to see how those local systems differ.

Rio Grande City H S accounts for 16.1% of all Rio Grande City public-school enrollment
That concentration means Rio Grande City-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.
Rio Grande City school enrollment varies 4.0× across entities
Rio Grande City school enrollment ranges from 420 students (lowest) to 1,670 students (highest), a spread of 1,250 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.
Rio Grande City reports 87.1% free-lunch eligibility
The reported share is at least 75%, indicating a high concentration of measured economic need. 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.
Rio Grande City student-teacher ratio is 13.9:1 — 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.
2 of Rio Grande City's 16 listed schools are charters
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.
