Summary:
ZIP code 54212 — Fish Creek, Wisconsin — contains just one high school, Gibraltar High, which serves grades 9–12 and enrolls about 175 students as part of the Gibraltar Area School District. Because it is the only high school in this ZIP code, parents cannot compare it against a local peer school; the most useful comparisons are between Gibraltar High and its district and Wisconsin statewide averages.
Gibraltar High is one of the top-performing high schools in Wisconsin: it earned 5 stars in every reported year and ranked 26th of 533 schools (95th percentile) in 2025–2026, 22nd of 431 (95th percentile) in 2024–2025, and 24th of 431 (94th percentile) in 2023–2024. Its district is also rated 5 stars, ranked 32nd of 432 districts. Proficiency is above the state average in every subject and year reported, with 2025–2026 results of 78.05% in Social Studies and 77.14% in English Language Arts — roughly 29–30 percentage points above Wisconsin — and 62.86% in Science and 60.00% in Math, about 17–20 points above the state. Graduation and dropout outcomes are exceptional: a 100.0% graduation rate and 0.0% dropout rate for 2024–2025, versus 92.0% and 1.1% statewide.
The main concern in the data is chronic absenteeism: Gibraltar High reports 21.5%, higher than the district's 11.2% and the state's 17.3%, which contrasts with its otherwise strong results. Context includes 28.57% free/reduced lunch, $29,993 per-student spending, and a 9:1 student-teacher ratio — favorable inputs that do not by themselves prove what causes the outcomes. Year over year, Social Studies, ELA and Science proficiency improved slightly while Math declined from 62.22% to 60.00%; with only 175 students, these percentages can shift easily from one class to the next. Overall, Gibraltar High appears academically strong, highly ranked, and successful on graduation and dropout measures, with absenteeism the most visible area to watch.
