Summary

Endeavor Charter School is a small public charter high school in Watertown, Wisconsin, serving grades 9–12 with just 46 students, and it belongs to the Watertown Unified School District. That district ranks 289th of 432 Wisconsin districts (33rd percentile, 2 stars), but Endeavor Charter School is a 5-star school that ranked 35th of 533 schools (93rd percentile) in 2025–2026. Its rank history shows a sharp climb: 239th of 390 (2 stars) in 2020–2021, then 5th of 431 (99th percentile) in 2023–2024, and 35th of 431 in 2024–2025.

Achievement is the headline. In 2025–2026, 10th-grade proficiency was 100% in Social Studies (district 44.4%, state 48.25%), 81.82% in English Language Arts, 72.73% in Science, and 45.45% in Mathematics — all above district and state. Social Studies and Science have been strong for multiple years, while math, though solid, trails top nearby schools such as Oconomowoc High and Lake Mills High. Endeavor also reported 100% graduation rates in 2024–2025 and several prior years with 0.0% dropout, at the ceiling among nearby schools. Notably, its low-income students ranked 6th of 335 (98th percentile, 5 stars) in 2024–2025, even as free/reduced-lunch eligibility rose to nearly 37%. By contrast, Watertown High, in the same district, ranked 316th of 533 (41st percentile, 2 stars).

Two things are worth watching. Chronic absenteeism was 19.6% in 2024–2025, above the district's 14.4% and the state's 17.3%, and above Watertown High (15.2%) and Hustisford High (5.3%) — though Endeavor's own 8.5% the year before suggests a spike rather than a trend. Endeavor also spent $8,677 per student, the lowest among comparison schools. With only 46 students, single-year percentages can swing widely, so the multi-year patterns matter most.
