Summary:
Zip code 55119 in Maplewood, Minnesota is home to a single high school: Sejong Academy Upper School, part of the Sejong Academy of Minnesota district. It is a combined middle and high school serving grades 6–12 with 136 students, so the middle-grade results below carry real weight in its overall numbers. The school operates in a context of high economic need — 85.29% of students were eligible for free or reduced-price lunch in 2024–2025 — with a student-teacher ratio of 22.7.
Results tell two very different stories. Completion metrics look strong: in 2023–2024 the school reported a 93.7% graduation rate and a 0.0% dropout rate, both matching its district, against state benchmarks of 84.9% and 4.2%. Rankings, however, have swung sharply — from 29th of 480 Minnesota high schools at the 94th percentile with 5 stars in 2023–2024, down to 310th of 450 with 2 stars in 2024–2025, then back up to 225th of 473 at the 52nd percentile with 3 stars in 2025–2026. In 2025–2026, all-grade proficiency was below state in every core subject: math 18.8% vs. 44.9%, reading 28.1% vs. 48.6%, and science 19.0% vs. 25.5%. The clearest bright spot is 11th grade math, at 38.9% proficient against the state's 35.3% — the only grade-level subject where the school exceeds Minnesota.
Middle grades are the weakest area: 7th grade math was 7.4% versus the state's 40.3%, 7th grade reading 15.4% versus 43.5%, 6th grade math 13.3% versus 39.5%, and 6th grade reading 27.6% versus 53.4%. All-grade reading fell from 40.91% in 2024–2025 to 28.1% in 2025–2026, a drop of 12.81 percentage points, while math and science improved only slightly, to 18.8% and 19.0%. Note that 2024–2025 school-level graduation and dropout figures are not available here, so the strong 2023–2024 completion results cannot be confirmed as ongoing.
