Summary:
Zip code 56178 covers Tyler, Minnesota, and is home to 2 public schools — an elementary building serving grades PK–5 and a secondary building serving grades 6–12 — with a combined enrollment of 646 students, all within the RTR Public Schools district, which ranks 158 of 458 in Minnesota (66th percentile, 3 stars).
RTR Secondary School is the stronger performer in this area. It earned 4 stars and ranked 144 of 473 (70th percentile) in 2025–2026, a rebound from the 49th percentile the year before. Its graduation rate was 97.9% versus the state's 84.9%, and its dropout rate was 0.0% versus the state's 4.2%. Reading (50% vs. 48.6%) and science (32.1% vs. 25.5%) were above state averages, and 8th graders beat the state in math, reading, and science. Math is the weak spot: all-grades math was 40%, below the district's 42.4% and the state's 44.9%.
RTR Elementary School shows a different and more concerning pattern. It has a favorable student-teacher ratio of 10.4 and all-grades math of 45.9%, slightly above the state's 44.9%, with 5th grade reading at 60% versus the state's 54.5%. But its rank has fallen three years running — 58th, then 49th, then 38th percentile — and it declined in all three subjects year over year. Reading is the biggest concern at 40.7%, below the district and state, with 3rd grade reading at 34% versus 46.8% and 4th grade at 31.1% versus 48.8%. Free/reduced lunch rates are similar at both schools (about 35–37%), so the performance gap is not explained by a large poverty difference.
