Summary

Ann Arbor Open at Mack School is a public K-8 school in Ann Arbor, MI, serving 508 students as part of the highly-rated Ann Arbor Public Schools district.

What truly sets Ann Arbor Open apart from nearby elementary schools is its unique K-8 structure. While most neighboring schools like Angell School or Bach Elementary School only serve through 5th grade, Ann Arbor Open offers a continuous pathway through middle school. This appears to be a significant advantage: the school's test scores in 6th, 7th, and 8th grades are exceptionally strong. For example, 8th-grade reading proficiency hit 88.6% and science reached 78.9%—far exceeding state averages. The school also shines in social studies, with 8th graders scoring 82.1% proficiency. Students here also show up consistently; the chronic absenteeism rate of 15.5% is less than half the district average of 35.7%, suggesting strong engagement and family involvement.

However, the picture is more nuanced in the early grades. In 3rd and 4th grade, math proficiency (around 49%) trails the district average (around 61%), and scores are generally lower than top K-5 schools like Angell or Bach. This suggests the school's greatest strength lies in building academic momentum as students mature. One area to watch is special education: after ranking in the 98th percentile in 2022-2023, that subgroup's performance dropped to the 39th percentile by 2025-2026—a dramatic shift worth investigating. Financially, the school spends about $18,892 per student, which is more than some high-performing peers but less than others like Abbot School ($39,965), suggesting efficient use of resources. Overall, Ann Arbor Open offers a compelling option for families seeking a stable, academically strong environment that carries students successfully through 8th grade.

What people are saying

by a parent
Thursday, June 29, 2023

Absolute bottom of the AAPS schools. It has progressively gone down hill in the last few years. It used to be an Open philosophy, where parents were welcome and contributed to the school. This past year, in particular, I have never felt so unwelcome in the office. The administration is anti-teacher and anti- parent. Children skip class every day with no accountability and when teachers try to ask for help, they are disciplined. BIPOC children are non- existent at that school because the school does not feel safe nor welcoming. In fact one BIPOC child was chocked unconscious by another child and basically nothing was done to the perpetrator. Children posting derogatory things on social media about teachers and students and nothing is done. Children defaming the school property, again nothing done. The school and the district claim to foster dignity, but that can’t be further from the truth . We are pulling our child for so many reasons and safety is the main one. Shame on you! Close Quote
