Summary:
ZIP code 56152 is served by a single elementary school: Red Rock Central Elementary, located at 509 S Birch St in Lamberton, MN. It serves grades PK–6 with 244 students and belongs to the Red Rock Central School District. Because it is the only elementary school in the ZIP code, there are no local peers to compare it against — the most meaningful benchmarks are its own district and the state of Minnesota. Available data cover school rank history for 2023–2024 through 2025–2026, MCA Math, Reading, and Science proficiency for 2025–2026 and 2024–2025, free/reduced lunch percentage, and student-teacher ratio.
The school stands out for its upward trajectory. In 2025–2026 it ranked 112 out of 869 Minnesota schools — the 87th percentile with 4 stars — up sharply from 272 out of 872 (69th percentile, 3 stars) in 2024–2025 and 315 out of 881 (64th percentile, 3 stars) in 2023–2024. That is a gain of 203 rank positions over two years. In 2025–2026, all-grade proficiency was 64.3% in Math, 65.8% in Reading, and 41.7% in Science, beating the district in every subject and the state by 19.4, 17.2, and 16.2 points respectively. Math posted the largest year-over-year gain, rising 12.58 points, while Reading and Science improved 1.45 and 4.56 points.
Grade-level results show where the strengths concentrate. Math was exceptionally strong in 3rd grade (87%) and 4th grade (89.7%), but by 6th grade it was 40%, just 0.5 points above the state. Reading was consistently strong across grades 3–6, ranging from 63.4% to 67.9% and at least 10 points above the state at every grade. Science is above state but below Math and Reading, and only 5th grade is reported, so that data base is narrower. Free/reduced lunch is 40.57%, and the student-teacher ratio is 12.9. Note that Reading exam labels changed from MCA-III in 2024–2025 to MCA-IV in 2025–2026, so year-over-year Reading comparisons deserve some caution.
