Summary:
RTR Secondary School in Tyler, MN is the only high school serving RTR Public Schools, a combined grades 6–12 building of 380 students in a small rural southeastern Minnesota community. The district is ranked 158 of 458 in Minnesota — 66th percentile with 3 stars — with 35.26% free/reduced lunch and a 14.3 student-to-teacher ratio in 2024–25. Because there is only one high school, the most useful comparisons are to state averages and to the school's own year-over-year trends.
Science is the school's clearest academic strength, beating the state in both years: 32.1% proficient all grades in 2025–26 versus 25.5% statewide, and 33.93% versus 26.15% in 2024–25. Eighth grade science stands out at 30% versus 16.7% state. Reading also improved, rising from 43.19% all grades in 2024–25 to 50% in 2025–26, now slightly above the state's 48.6%, with 10th grade reading at 57.1% versus 42.5% and 8th grade reading at 60% versus 50%. The pattern is uneven, though: 6th and 7th grade reading remain below state. Math is the main concern — all-grade math slipped from 45.28% in 2024–25 to 40% in 2025–26, which is 4.9 points below the state; 8th grade math is strong at 50% versus 42.3%, while 11th grade math trails at 31.6% versus 35.3%.
Graduation outcomes are excellent: a 97.9% graduation rate and 0.0% dropout rate, far ahead of the state's 84.9% and 4.2%. Rank history is volatile, however: 87th percentile with 4 stars in 2023–24, down to 49th percentile with 2 stars in 2024–25, then back up to 70th percentile with 4 stars in 2025–26, suggesting year-to-year variability possibly driven by cohort differences.
