Summary:
The Thornapple Kellogg School District contains one middle school, Thornapple Kellogg Middle School, which serves grades 6 through 8 in Middleville, Michigan, with an enrollment of 693 students.
For parents considering this school, the most important takeaway is that Thornapple Kellogg Middle School is a solidly above-average school that has recently experienced a noticeable dip in test scores. The school’s state ranking fell from the 73rd percentile (4 stars) in 2024-2025 to the 65th percentile (3 stars) in 2025-2026, driven by declines across nearly every subject. For example, 6th grade ELA proficiency dropped from 48.8% to 36.9%, and 6th grade math fell from 35.7% to 30.0%. Despite these drops, the school still outperforms the state average in several areas, most notably in 8th grade PSAT ELA, where 80.1% of students are proficient compared to the state’s 64.8%—a remarkable 15.3-point advantage. However, math remains a persistent challenge, with proficiency hovering around 30-35% across all grades, mirroring a broader statewide issue but still representing a key area for growth.
On the positive side, chronic absenteeism at 14.3% is less than half the state average of 27.9%, though it is slightly higher than the district’s 12.0%. The school serves a moderate-to-high proportion of economically disadvantaged students (39.11% free/reduced lunch), yet it generally beats state averages, suggesting effective instruction that helps mitigate socioeconomic hurdles. Per-student spending is $14,519 with a student-teacher ratio of 17.6:1, which is reasonable but not exceptional. The year-over-year score declines across all subjects are unusual and could stem from testing changes, curriculum shifts, or cohort differences—parents should watch next year’s data to see if this is a trend or a one-year anomaly. Overall, this is a dependable school with strong literacy outcomes, but families should be aware of the recent downward trajectory and the ongoing math gap.
