Summary:
Zip code 48442 is home to just one high school, Holly High School, which serves grades 9 through 12 and enrolls about 1,001 students in the Holly Area School District.
For parents, the most important takeaway is that Holly High School is a solidly average performer statewide, ranking 381st out of 800 Michigan high schools (52nd percentile) with a 3-star rating. The school does a commendable job keeping students enrolled—its dropout rate of 3.6% is less than half the state average of 7.1%, and its graduation rate of 86.2% edges out the state’s 84.0%. However, academic performance has been volatile. After jumping to the 66th percentile in 2024-2025, the school fell back to the 52nd percentile in 2025-2026, with declines across nearly every subject test. SAT math proficiency sits at just 24.5% (below the state’s 26.5%), and reading proficiency is 51.8%, nearly matching the state. Science (31.4%) and social studies (36.8%) both trail Michigan averages by roughly 4 to 6 percentage points.
The most glaring concern is math. Proficiency rates hover in the mid-to-high 20s across all grade levels on both the PSAT and SAT, indicating a systemic issue that starts early in high school and never recovers. Equally troubling is chronic absenteeism: 34.7% of students miss significant school days, well above the district average of 28.4% and the state’s 27.9%. This is a paradox—students aren’t dropping out, but a large portion are disengaged enough to miss class, which likely fuels the recent test score declines. On the positive side, the school spends a healthy $15,526 per student, suggesting resources are available. If you’re considering this school, focus on how the district plans to tackle math intervention and absenteeism, as these two issues appear to be the biggest barriers to consistent improvement.
