Summary:
Zip code 49067 is home to just one middle school, Marcellus Middle School, which serves grades 6-8 within the Marcellus Community Schools district, a small, rural area where the school enrolls 136 students and 58% qualify for free or reduced lunch.
Because this is the only middle school in the area, its performance directly reflects the district. The most important thing for parents to know is that this school experiences dramatic swings in test scores from year to year, largely because its small size means each incoming class has an outsized impact on overall results. For instance, the school jumped to the 79th percentile statewide in 2024-25, then fell to the 54th percentile in 2025-26. This volatility is not necessarily a sign of declining instruction; rather, it tracks specific cohorts. The 8th-grade class that left in 2025 was exceptionally strong, while the current 8th graders are weaker in math. Looking at the same group of students over time, however, reveals genuine growth: the cohort that was in 6th grade in 2024-25 improved dramatically by 7th grade in 2025-26, jumping 23.5 points in ELA (to 50% proficiency, which is 11.6 points above the state average) and 11.6 points in math.
There are clear bright spots and challenges. Chronic absenteeism is a standout positive at just 16.2%, far better than the district (26.7%) and state (27.9%), indicating strong student engagement. Seventh-grade ELA is a notable strength, exceeding state averages. However, math remains a persistent weakness, especially in 6th grade where only 24.5% of students are proficient, and the school also trails the state in 8th-grade social studies and PSAT ELA. With a student-to-teacher ratio of 23.4:1 and per-student spending of $11,793, class sizes are relatively large, which may limit individualized attention. Overall, parents should expect year-to-year ranking shifts but can take comfort in strong attendance and clear academic growth for students as they move through the grades.
