Summary:
The Westosha Central Union High School School District is a one-school district in Salem, Wisconsin, serving grades 9–12 through a single campus, Central High, with 1,309 students — roughly 327 per grade. Because it is a union high school district, it operates no elementary, middle, or alternative schools; all students arrive from outside feeder districts, so there is no sibling school to offset a weak class and no district-versus-school gap to compare.
Completion and engagement are the strongest parts of the profile. Central High graduates 97.5% of students versus 92.0% statewide (+5.5 points), reports a 0.0% dropout rate against the state's 1.1%, and has 12.8% chronic absenteeism compared with 17.3% statewide — about 26% lower in relative terms. With a senior class of roughly 327, the 97.5% rate implies about 8 students not graduating on time, and 12.8% absenteeism means roughly 168 chronically absent students.
Academically, Central High sits above the state in all four tested 10th-grade subjects in 2025‑26: Social Studies 58.86% vs. 48.25% (+10.61), Math 48.18% vs. 42.93% (+5.25), ELA 49.39% vs. 48.47% (+0.92), and Science 44.55% vs. 43.20% (+1.35), a four-subject average edge of +4.53 points. Math has been the most durable strength across both tested years (+10.50 average margin); Science the narrowest (+3.09). Social Studies moved from the only subject trailing the state in 2024‑25 (46.79% vs. 47.67%) to the largest overperformance a year later — but since these are different groups of students, that is a cohort difference rather than proven improvement or decline. The district ranks 147 of 432 (66th percentile, 3 stars); per-student spending is $14,273 with an 18.5:1 student–teacher ratio and 12.3% free/reduced lunch.
