How the Janesville Public-School Landscape Breaks Down
Janesville, WI enrolls 9,751 students across 25 public schools reporting to the National Center for Education Statistics. Of those, 4 are charter schools, giving families genuine alternatives to the traditional neighbourhood assignment model. The average student-teacher ratio across the city is 13.5:1, Schools must report at least five campuses in a city to appear in this listing, which is why very small towns may redirect to the broader county or state view.
The highest-ranked campus in Janesville is Craig High, scoring 29/100 (F) with 1,400 enrolled students at the high level. Families should treat any single ranking as a starting point rather than a verdict — a school serving fewer at-risk students or offering more AP classes will score higher on resource-based composites even if individual teachers or programs elsewhere are stronger. The quality score framework is transparent and rebuilt from raw NCES and Civil Rights Data Collection (CRDC) inputs, so each component can be inspected on the individual school pages linked in the table below.
Janesville schools sit within multiple district boundaries, which matters for property taxes, redistricting votes, and bond measures. Each district files its own NCES F-33 financial return, meaning per-pupil spending can vary noticeably even between neighbouring campuses in the same city. Use the table to sort by enrollment, level, or district, then click any school name for campus-level demographics, Title I status, counselor and nurse staffing, AP courses, chronic-absenteeism rates, and district per-pupil spending. The sidebar links also connect Janesville housing costs, wage data, and crime statistics — context many parents weigh alongside test-adjacent school signals when relocating.
Janesville school enrollment varies 140× across entities
Janesville school enrollment ranges from 10 students (lowest) to 1,400 students (highest), a spread of 1,390 students. That ratio is among the widest observed and reflects extreme heterogeneity inside a single city — small specialty programs sit alongside large comprehensive campuses, often serving very different family demographics inside walking distance. Per-school staffing, programme depth, and capital-renovation cycles often diverge inside the same city based on enrollment shape — a 200-student magnet runs a different operational model than a 2,000-student comprehensive high school.
Janesville has higher-than-average Title I eligibility — 50.3% of the population qualifies for free or reduced-price lunch
free or reduced-price lunch eligibility is the federal threshold for Title I funding allocations, established under the Every Student Succeeds Act (ESSA, 2015). Areas above 75% eligibility receive concentration grants on top of the basic Title I formula. Regions with eligibility this high typically draw a substantially larger federal funding share relative to their local tax base, which can either offset or reinforce existing gaps depending on allocation policy.
Janesville student-teacher ratio is 13.5:1 — 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.
Janesville has higher-than-average charter school authorisation eligibility — 16.0% of the population qualifies for charter-school enrollment options
charter-school enrollment options eligibility is the federal threshold for charter school authorisation funding allocations, established under the state-specific charter law. Areas above 30% eligibility receive concentration grants on top of the basic charter school authorisation formula. Regions with eligibility this high typically draw a substantially larger federal funding share relative to their local tax base, which can either offset or reinforce existing gaps depending on allocation policy.
