Summary

Sejong Academy Upper School is a small public charter school in Maplewood, Minnesota, serving 136 students in grades 6–12 as part of Sejong Academy of Minnesota. In 2025–26 it ranked 225 of 473 state schools — the 52nd percentile with 3 stars — ahead of its district's 328 of 458 (28th percentile, 1 star). Its rank history swings widely: 94th percentile in 2023–24, 31st in 2024–25, and 20th in 2020–21. Roughly 85% of students qualified for free or reduced lunch in 2024–25, far above most nearby schools, and its student-to-teacher ratio rose to 22.7 from 10.3 the prior year.

All-grade proficiency was 18.8% in math, 28.1% in reading and 19.0% in science — below the state's 44.9%, 48.6% and 25.5%, but comparable to or better than nearby schools. Those all-grade figures blend middle and high school, hiding two different stories. At the high-school level, 11th-grade math was 38.9%, above the state's 35.3% and far above North Senior High (10.8%), Tartan Senior High (19.2%), Harding Senior High (8.2%) and Twin Cities Academy (9.1%). End-of-course science was 31.3%, below the state's 35.0% but above every nearby school reporting it, while 10th-grade reading (33.3%) trailed the state and Tartan. Middle school is the weak spot: 7th-grade math was 7.4% and 7th-grade reading 15.4%.

The biggest bright spot is the low-income subgroup: Sejong ranked 36 of 377 schools statewide (90th percentile, 5 stars) in 2025–26, up from the 74th percentile in 2024–25 — notable for a school where about 85% of students are low-income. Graduation results are strong but uneven: 93.7% with a 0.0% dropout rate in 2023–24, versus 81.8% and 4.5% in 2022–23; 2024–25 school-level figures are not available. With only 136 students, small changes can move rankings sharply. Sejong's 52nd-percentile rank still outpaces every nearby ranked school — Tartan (35th), North (23rd), Twin Cities Academy (15th) and Harding (13th).
