Summary
Rocketship Stellar Elementary is a PK–5 charter school at 2431 S 10th St on Milwaukee's south side, part of Rocketship Education Wisconsin Inc, a district ranked 416 of 432 statewide. The state reports an enrollment of 0 students, but that figure conflicts with the school's own test-score record and appears to be a reporting error rather than an empty building. It sits among roughly ten schools within about 1.15 miles — mostly Milwaukee School District elementaries such as Hayes Bilingual School, Riley Dual Language Montessori School, and Lincoln Avenue Elementary — plus the much higher-performing Downtown Montessori.
By state standards, Rocketship Stellar ranks 905 of 1,039 schools (13th percentile, 1 star). Its clearest strength is math in grades 3 and 5: 50% proficiency in 3rd grade and 38.24% in 5th, both the highest among the listed nearby schools, including Downtown Montessori. The results are uneven, though — 4th-grade math falls to 22.22% — and English/language arts is weak at every tested grade: 16.67% in 3rd, 18.52% in 4th, and 20.59% in 5th, against a state average near 53%. Fourth-grade science (18.52%) and social studies (37.04%) also trail state levels. Within its immediate neighborhood, Rocketship edges out a very low-performing group of Milwaukee schools (ranked 924–996), but Downtown Montessori is far ahead at 420 of 1,039 (60th percentile, 3 stars).
Subgroup results suggest the school is relatively more effective with English Language Learners, whose rank reaches the 49th percentile — near the statewide median and well above the school's overall 13th percentile. Hispanic students and students with disabilities sit at the 35th percentile, while low-income students and female students rank lowest, at the 10th percentile. Important context is missing: free/reduced-lunch rates, student-teacher ratios, chronic absenteeism, and spending are not reported. Nearby schools report chronic absenteeism of roughly 17% to 54%, while Downtown Montessori reports 8.2%. The takeaway for families: promising 3rd- and 5th-grade math, but reading, science, and overall results remain in the bottom tier of Wisconsin schools.
