Summary:
Zip code 48133 is home to just one middle school, Mason Middle School, which serves grades 6 through 8 and is part of the Mason Consolidated Schools (Monroe) district, with a modest enrollment of 223 students.
For parents considering this area, the standout takeaway is that Mason Middle School is a high-performing school that consistently beats state averages in every subject and grade level tested. In the 2025-2026 school year, it ranked in the 84th percentile statewide (142nd out of 896 Michigan middle schools) and earned a 4-star rating. The school’s greatest strength is mathematics, where 6th and 7th graders post proficiency rates roughly 15 points higher than the state average (47.2% vs. 31.9% in 6th grade math, for example). English Language Arts is also a clear asset, with 8th graders achieving a 75% proficiency rate on the PSAT 8 ELA exam—more than 10 points above the state. The school also benefits from a favorable student-teacher ratio of 14.3:1 and per-student spending of $15,382, which supports more individualized instruction.
However, there are a few nuances worth noting. While 6th and 7th grade math scores are excellent, 8th grade math on the PSAT 8 drops to 39.1% proficient—still above the state average of 33.2%, but noticeably weaker than the school’s own lower-grade performance. Additionally, chronic absenteeism sits at 23.4% of students, which is better than the district (25.7%) and state (27.9%) averages, yet still means nearly a quarter of students are missing significant instructional time. Given that only 32.74% of students qualify for free or reduced lunch, the school serves a relatively advantaged population, and its strong results suggest that attending students are thriving—but improving attendance could unlock even greater potential for the entire student body.
