Summary:
Zip code 49093 is served by a single high school, Three Rivers High School, part of the Three Rivers Community Schools district, which enrolls 632 students in grades 9-12.
For parents considering this area, Three Rivers High School presents a mixed but generally positive picture. The school’s greatest strength is its exceptional graduation rate of 95.2%, far exceeding the state average of 84.0%, while its dropout rate of 3.3% is less than half the state’s 7.1%. Chronic absenteeism (24.5%) also sits below the state average (27.9%), suggesting strong student engagement. Academically, the school outperforms state averages in science (38.1% proficient vs. 35.2%), social studies (47.6% vs. 43.2%), and 11th-grade reading/writing on the SAT (53.7% vs. 52.1%). Its state ranking has improved steadily, moving from the 53rd percentile in 2023-2024 to the 61st percentile for 2025-2026, indicating positive momentum.
However, the most significant concern is mathematics. The school trails the state average by 8.8 percentage points on the 11th-grade SAT math exam (17.7% vs. 26.5%) and by 6.6 points on the 9th-grade PSAT math (26.9% vs. 33.5%). This math gap persists from early high school through the college entrance exam, creating a paradox: students graduate at high rates, yet a large majority are not meeting college-readiness benchmarks in math. With a per-student spending of $20,141 and a student-teacher ratio of 18.2:1, the school has solid resources, which appear to support strong outcomes in humanities and sciences but have not yet translated into math success. Parents should weigh the school’s excellent graduation culture and improving overall performance against this notable academic weakness in mathematics.
