Summary:
The Detroit Achievement Academy district in Detroit, Michigan, operates two K-8 charter schools—Detroit Prep and Detroit Achievement Academy—serving a combined 770 students, but the two campuses deliver vastly different academic results despite sharing the same network.
Detroit Prep is the clear standout, earning a 3-star rating and ranking in the 67th percentile statewide. It outperforms its sister school by wide margins in nearly every subject and grade—for example, 3rd grade ELA proficiency is 49% at Detroit Prep versus just 12.8% at Detroit Achievement Academy. Detroit Prep also excels in upper grades, with 8th grade PSAT math proficiency at 61.8% (nearly double the state average) and 8th grade science at 58.8% versus the state's 39.2%. Meanwhile, Detroit Achievement Academy holds only a 1-star rating and ranks in the 23rd percentile, struggling most in early elementary grades. However, it shows a "middle school recovery" pattern—by 7th grade, its ELA proficiency (52%) and math proficiency (44%) both exceed state averages.
Demographics help explain some of the gap: Detroit Achievement Academy serves a higher-poverty population (84.4% free/reduced lunch) with higher chronic absenteeism (18.2%) compared to Detroit Prep (54.6% and 11.1%, respectively). Notably, Detroit Achievement Academy actually spends more per student ($12,938 vs. $12,135) yet achieves worse outcomes, suggesting funding isn't the issue. Both schools exceed state averages in 7th grade ELA, hinting at effective middle school programming. Parents should also note the district's overall 3-star rating masks this stark internal divide—and that year-to-year scores at Detroit Achievement Academy swing dramatically, possibly due to small cohorts. For families, Detroit Prep is the stronger choice academically, while the flagship campus offers pockets of promise in later grades.
