Summary:
Zip code 49240 is home to just one middle school, Grass Lake Middle School, which serves grades 6 through 8 within the Grass Lake Community Schools district, enrolling 290 students in a single-school area.
For parents, Grass Lake Middle School is a solid, above-average choice. It currently ranks 252nd out of 896 Michigan middle schools, placing it in the 72nd percentile with a 4-star rating. The school’s biggest academic strength is English Language Arts and Social Studies. In 8th grade, PSAT ELA proficiency hits an impressive 74.7%, far above the state’s 64.8%, and Social Studies proficiency is 60.7% versus the state’s 50.3%. Science also outperforms the state (47.6% vs. 39.2%). However, math is a clear weak spot—proficiency rates hover near state averages (around 33-34% in most grades), creating a stark divide where ELA scores are more than double math scores in 8th grade. There is also a notable grade-level anomaly: 6th-grade ELA proficiency (47.9%) is dramatically higher than 7th-grade (34.8%), a much larger drop than the state’s typical pattern, which could point to a strong cohort or a curriculum issue in 7th grade.
Looking at the bigger picture, the school has shown an upward trend in state ranking over the past three years, jumping from 331st in 2023-2024 to 220th in 2024-2025, before settling at 252nd this year—a slight dip that suggests a possible plateau. One concern is chronic absenteeism: at 24.3%, it affects nearly one in four students, which is higher than the district’s 19.3% rate, though still below the state’s 27.9%. With per-student spending of $13,867 and a student-teacher ratio of 15.4:1, the school invests heavily in its students, but the data suggests those resources are yielding strong results in literacy and social studies while leaving math performance merely average—an area where parents might want to seek additional support or ask about intervention programs.
