Summary:
ZIP code 54923 contains exactly one high school: Berlin High, serving grades 9–12 with 441 students as part of the Berlin Area School District in Berlin, Wisconsin. Because it is the only high school in the area, every area-level result reflects this one school. The district carries a 1-star rating and ranks 351st of 432 in Wisconsin, placing it in the 19th percentile.
Berlin High's clearest strengths are in attainment. Its graduation rate of 93.6% in 2024–2025 is above the state's 92.0%, and its dropout rate of 0.9% is below the state's 1.1%. In 2024–2025, 10th-grade ACT ELA proficiency was 52.94%, above the state average of 48.62%, while science proficiency was 40.2% against the state's 43.42%. The school spends $17,908 per student, has a 12:1 student-teacher ratio, and 39% of students are eligible for free or reduced lunch.
Challenges center on attendance and the most recent test scores. Chronic absenteeism was 21.4% in 2024–2025 — above the district's 18.0% and the state's 17.3% — meaning roughly one in five students was chronically absent. In 2025–2026, Berlin High fell below the state in all four reported subjects, with the widest gap in social studies (31.96% proficient versus the state's 48.25%). ELA dropped to 37%, which is 11.47 points below the state, and math and science gaps widened as well. Rank history shows some movement — the 11th percentile in 2023–2024, 29th in 2024–2025, and 26th in 2025–2026 — but the school still holds a 1-star rating.
