Summary:
Zip code 53074 in Wisconsin is served by exactly one public high school: Port Washington High, which enrolls 809 students in grades 9–12 and belongs to the Port Washington-Saukville School District. Because it is the only high school in the area, there is no local comparison to make — the story here is simply how this one school performs, and the answer is very well.
Port Washington High ranks 43rd out of 533 Wisconsin high schools in 2025–2026, placing it in the 92nd percentile with a 5-star rating, and it held that same 92nd-percentile, 5-star standing in 2024–2025 after improving from the 84th percentile and 4 stars in 2023–2024. Its test scores beat the state in every subject in both years. In 2025–2026, 10th graders reached 70.21% proficiency in Social Studies, 66.67% in English Language Arts, 58.47% in Mathematics, and 59.02% in Science, advantages of +15.54 to +21.96 points over the state. Averaged across the four subjects, the school scored 63.59% versus the state's 45.71%. One caution: Mathematics fell from 64.36% to 58.47% year over year, and Science dipped about 2.9 points, while Social Studies rose nearly 3.9 points.
Completion outcomes are strong. The graduation rate is 95.8%, above the state's 92.0%, and the dropout rate is 0.5% — less than half the state's 1.1%. Chronic absenteeism is 15.4%, below Wisconsin's 17.3% but noticeably higher than the district's 9.6% (a figure that includes elementary and middle grades); it represents roughly 125 students. Per-student spending is $15,264, the student-teacher ratio is 14.7, and about 24.23% of students qualify for free or reduced lunch. Overall, families are looking at a consistently high-performing, top-decile school, with math achievement and absenteeism the areas to watch.
