Summary:
Zip code 49093 is home to just one middle school, Three Rivers Middle School, which serves grades 6-8 and enrolls 476 students within the Three Rivers Community Schools district.
For parents considering this school, the most important takeaway is that Three Rivers Middle School shows a mix of strengths and challenges. The school’s 8th graders actually outperform the state average on the PSAT English Language Arts test (68.7% proficient vs. 64.8% statewide), and they essentially match the state in 8th-grade social studies (50.0% vs. 50.3%). However, math is a consistent weak spot: proficiency rates on both the M-Step and PSAT math tests run several points below state averages, with only 26.7% of 8th graders proficient on PSAT math compared to 33.2% statewide. The most alarming trend is a sharp 9.6-point drop in 6th-grade ELA proficiency over the past year, falling to just 17.9%—nearly 20 points below the state average. Meanwhile, 7th-grade ELA improved slightly to 24.2%, but still trails the state by 14 points.
The school’s overall ranking has slipped from the 57th percentile (3 stars) in 2023-24 to the 47th percentile (2 stars) in 2025-26, reflecting three straight years of decline. This is notable given that the school spends a very high $26,667 per student and maintains a favorable 14.4:1 student-teacher ratio. Chronic absenteeism sits at 28.0%, just above the state rate of 27.9%, which may be undermining the benefits of smaller classes. On a positive note, the school’s success in PSAT ELA and social studies suggests that certain instructional approaches are working well and could be replicated in math and younger-grade reading. Parents should watch the 6th-grade ELA decline closely, as it may signal a cohort-specific issue or curriculum challenge that needs immediate attention.
