Summary:
Zip code 53930 covers Endeavor, Wisconsin, and contains exactly one public school: Endeavor Elementary, an elementary school serving grades K–5 in the Portage Community School District, with 57 students enrolled. There are no middle, high, or alternative schools in this zip code, so older students must attend school elsewhere in the district.
The school stands out sharply against its district. The Portage Community School District is ranked 244 of 432 in Wisconsin, at the 44th percentile with 2 stars, while Endeavor Elementary has ranked much higher: 26 of 1,061 (98th percentile, 5 stars) in 2023–24, 107 of 1,044 (90th percentile, 4 stars) in 2024–25, and 270 of 1,039 (74th percentile, 4 stars) in 2025–26. Its average proficiency across the eight listed tests is about 75.4% in 2025–26, versus 54.7% statewide and 51.8% in the district, and about 87.6% in 2024–25, versus 54.0% statewide and 48.0% in the district. The school outperformed the district on every listed test in both years and beat the state on 7 of 8 tests each year. Math is the most consistent strength: about 85.0% in 2025–26 versus 53.1% for the state, and about 92.3% in 2024–25 versus 53.8%, with grade 5 math at 100% both years. Science is the relative weak spot in 2025–26 at 53.85%, essentially at the state average of 53.46%.
Chronic absenteeism is a clear advantage: 12.5% at the school in 2024–25, compared with 20.4% in the district and 17.3% statewide. The school also reports a 33.33% free/reduced-lunch rate, $17,414 in per-student spending, and a 12.2 student-teacher ratio. Because enrollment is only 57 students, a single student can move a grade-level percentage by roughly 7–14 points, so year-to-year swings should be read with caution — the rank slippage from exceptional to still-strong is real, but the school remains well above its district and usually above the state.
