5 public K-12 schools in Grantsburg 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, Grantsburg has more public-school enrollment than 11% of the 4,487 US cities in this directory. Iforward enrolls 52.9% of Grantsburg's public-school students. That is enough concentration for one institution to pull the citywide enrollment, staffing, and Resource Index averages toward its own profile. The smaller campuses below should therefore be compared directly rather than inferred from the headline mean; their grade configurations and program footprints can be materially different even inside the same district.
Combined-grade campuses shape the local portfolio
2 of Grantsburg's 5 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 13-point gap between Iforward and Grantsburg Middle shows the range hidden by Grantsburg'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.

Iforward accounts for 52.9% of all Grantsburg public-school enrollment
That is an overwhelming concentration, leaving the rest of Grantsburg a distant remainder — means Grantsburg-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. Because it contains a majority of the affected population, enrollment-weighted aggregates will sit closer to this entity's reported fields than to those of smaller peers; an unweighted entity count answers a different question.
Grantsburg school enrollment varies 8.8× across entities
Grantsburg school enrollment ranges from 117 students (lowest) to 1,030 students (highest), a spread of 913 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.
Grantsburg operates one school district — a single-district system
Grantsburg'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.
Grantsburg student-teacher ratio is 16.6:1 — 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 Grantsburg is typically wider than the Grantsburg-aggregate figure suggests.
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 Grantsburg
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 Grantsburg school has the highest Resource Investment Index? ▼

How many schools are in Grantsburg, WI? ▼
Grantsburg has 5 public schools with a total enrollment of 1,948 students. 1 are charter schools. Average student-teacher ratio: 16.6:1.
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.
