Summary:
Arbor Preparatory High School is the sole school in its district, serving grades 9-12 in Ypsilanti, Michigan, with 278 students and a student-teacher ratio of 14.7:1.
For parents considering this school, the most important takeaway is that Arbor Preparatory High School offers a small, resource-rich environment—spending $19,744 per student—but academic outcomes are currently below state averages across nearly every subject. In the 2025-2026 school year, only 14% of 11th graders were proficient in SAT Math (state: 26.5%), and just 43.9% met the bar in SAT Reading/Writing (state: 52.1%). The school also saw a sharp, universal decline in test scores from the prior year, with SAT Reading/Writing dropping 10.8 percentage points and science falling 9.0 points. Mathematics is a particular weakness at every grade level, with proficiency rates in the low teens for 9th, 10th, and 11th graders—roughly half the state average. Social Studies is the relative bright spot, with a gap of only 2.1 points below the state and stable year-over-year performance.
Beyond academics, the school faces significant challenges with attendance and retention. Chronic absenteeism affects 37.3% of students (state: 27.9%), the dropout rate is 13.8%—nearly double the state average—and the graduation rate stands at 76.9% versus 84.0% statewide. Over half of the student body (56.83%) qualifies for free or reduced lunch, indicating a predominantly low-income population. The school’s state ranking has been volatile, swinging from the 19th percentile in 2023-2024 to the 51st percentile in 2024-2025, then back down to the 30th percentile in 2025-2026. While the high per-student spending and small class sizes provide a foundation for improvement, the combination of low math proficiency, high absenteeism, and declining test scores suggests that targeted interventions—especially in mathematics and student engagement—are urgently needed to reverse the current trajectory.
