10 public K-12 schools in Delta 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, Delta has more public-school enrollment than 25% of the 4,487 US cities in this directory. Delta has fewer enrolled students than most listed city systems, but its student-teacher ratio still falls on the more crowded side of the national distribution. That pairing rules out a simple “large city” explanation for the staffing load. Campus size, grade configuration, vacancies, and district boundaries become the more relevant questions; the profiles below expose those fields school by school without turning the ratio into a quality verdict.
A full K–12 ladder sits inside the city boundary
Delta's list includes 4 elementary, 1 middle, and 2 high-school campuses, plus 3 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.
A small portfolio contains radically different campus scales
Delta lists only 10 schools, yet reported enrollment runs from 14 to 626 students, a 45-fold range. In a portfolio this compact, the smallest record may be a specialized or nonstandard setting rather than a miniature version of the largest campus. That distinction affects how ratios and program fields should be read. Compare similarly configured grade levels first; combining the extremes into one city average conceals more than it explains.

Delta High School accounts for 22.7% of all Delta public-school enrollment
That concentration means Delta-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.
Delta school enrollment varies 45× across entities
Delta school enrollment ranges from 14 students (lowest) to 626 students (highest), a spread of 612 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.
Delta operates one school district — a single-district system
Delta'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.
Delta student-teacher ratio is 20.3:1 — high (typically associated with larger urban scale or staffing constraints that have widened the headcount gap)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
20% 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 Delta
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.
Which Delta school has the highest Resource Investment Index? ▼
Backpack Early Learning Academy has the highest Resource Investment Index among the Delta schools in this federal-data comparison at 65/100. The index summarizes reported staffing, counseling, gifted-program, and attendance inputs; it is not an academic rating.
How many schools are in Delta, CO? ▼
Delta has 10 public schools with a total enrollment of 2,761 students. 2 are charter schools. Average student-teacher ratio: 20.3:1.
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.
