9 public K-12 schools in Irmo 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, Irmo has more public-school enrollment than 61% of the 4,487 US cities in this directory. Irmo lands in the upper national tier on both the average Resource Investment Index and teacher staffing intensity. Those measures come from different inputs: the index combines reported counselors, gifted access, attendance, and staffing, while the staffing percentile compares the city's student-teacher ratio directly. Agreement across both measures is stronger evidence of broad reported capacity than either score alone, though neither is a test-score rating or a guarantee about an individual classroom.
Combined-grade campuses shape the local portfolio
5 of Irmo's 9 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 7-point gap between Oak Pointe Elementary and H. E. Corley Elementary shows the range hidden by Irmo'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.

Dutch Fork High accounts for 29.6% of all Irmo public-school enrollment
That dominant concentration means Irmo-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.
Irmo school enrollment varies 6.6× across entities
Irmo school enrollment ranges from 258 students (lowest) to 1,703 students (highest), a spread of 1,445 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.
Irmo student-teacher ratio is 10.8:1 — 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.
11% 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 Irmo
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 Irmo school has the highest Resource Investment Index? ▼

How many schools are in Irmo, SC? ▼
Irmo has 9 public schools with a total enrollment of 5,746 students. 1 are charter schools. Average student-teacher ratio: 10.8:1.
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.
