Summary
Grantosa Drive Elementary is a PK–8 school serving 506 students at 4850 N 82nd St in Milwaukee, making it one of the larger elementary/middle schools in its immediate neighborhood. It is part of the Milwaukee School District, which ranks 418th of 432 districts in Wisconsin, and Grantosa Drive Elementary's own 2025–2026 rank is 975th of 1,039 state schools — the 6th percentile, with 0 stars. About 91.7% of students qualify for free or reduced-price lunch, and chronic absenteeism is 61.7%, far above the district's 46.2% and more than three times Wisconsin's 17.3%. Per-student spending is $19,924 and the student-teacher ratio is 17.9.
Average proficiency in 2025–2026 is ELA 12.4%, math 14.8%, social studies 19.2% and science 11.5%, below both district and state averages in every subject. Among nearby high-poverty schools, Grantosa outperforms Lancaster Elementary, Emerson Elementary, Kilbourn Elementary and Browning Elementary in ELA and math, though it trails Bryant Elementary in ELA and Craig Montessori School, Milwaukee German Immersion and Madison Elementary in every major subject. Third grade is a bright spot, with ELA at 23.68% and math at 34.21%, both above district averages, but 4th grade ELA drops to 6.98% and math to 4.65%. Subgroup results vary widely: the school's African American student group ranked in the 56th percentile with 3 stars, while special education students ranked in the 2nd percentile.
The school has improved from a very low base, with average ELA rising from about 3.0% in 2022–2023 to 12.4% and math from about 3.2% to 14.8%; its 6th percentile rank is its best in the available record. Attendance remains the biggest challenge — nearby schools with far lower absenteeism, such as Craig Montessori, Milwaukee German Immersion and Madison Elementary, post much higher test scores, as does Bryant Elementary among high-poverty peers. Spending has risen nearly 40% since 2019–2020, suggesting funding alone is not the deciding factor. For families, Grantosa shows real progress and some strong early-grade results, but middle-grade achievement and attendance are the areas to watch.
