Green Tree Preparatory Academy

Green Tree Preparatory Academy is a Milwaukee public school at 6850 N 53rd St, serving about 535 students in grades 6–12 as part of the Milwaukee School District. In 2025–26 it ranked 510th of 533 high schools statewide (4th percentile, 0 stars), a slight improvement from the bottom but still in Wisconsin’s lowest tier; it is mid-sized among nearby schools, larger than small alternatives like Banner Preparatory School of Milwaukee and ASSATA High, similar to Carmen Mid/High Northwest Campus, and smaller than King International, Brown Deer Middle/High, and Nicolet High.

Test proficiency is very low. In grades 6–8 ELA, proficiency was 5.56%, 5.71%, and 4.44%; math was 9.26%, 6.06%, and 0%. Grade 10 ACT proficiency was 2.38% in ELA, 7.14% in math, and 0% in science. These are far below district and state averages. Chronic absenteeism is severe: 80.9% of students were chronically absent in 2024–25, versus 46.2% in the district and 17.3% statewide. That is similar to Harold S Vincent School of Agricultural Science, Marshall High, and James Madison Academic Campus, but much higher than King International (38.2%), Brown Deer Middle/High (36.5%), and Nicolet High (2.8%).

Graduation is the clearest positive trend, rising from 40.9% in 2022–23 to 54.1% in 2023–24 and 85.7% in 2024–25—above the district’s 71.5% but below the state’s 92.0%. The dropout rate is relatively low at 2.1%, below the district’s 4.0% but above the state’s 1.1%. Green Tree’s graduation rate is above most same-district peers, though below King International, and far behind Brown Deer Middle/High (94.4%) and Nicolet High (96.9%). Per-student spending is $17,296, mid-pack nearby, and the student-teacher ratio improved to 22.3 but remains higher than most neighbors. Special education students rank highest among subgroups (30th percentile, 2 stars), while low-income and male students rank near the bottom statewide (2nd percentile); all groups remain below state norms.
