Summary:
ZIP code 55921 in southeastern Minnesota is home to one reported elementary school: Caledonia Elementary, which serves grades PK–5 with 295 students as part of Caledonia Public School District. Since it is the only elementary school in this area, there is no local peer to compare it with — but it stands out on its own merits. The district ranks 15th of 458 in Minnesota, placing it in the 97th percentile with 5 stars, a top-3% rating statewide. The school itself has earned 4 stars in each of the past three years, ranking between roughly the top 10% and top 17% of Minnesota elementary schools.
On the 2025–2026 state tests, Caledonia Elementary outperformed Minnesota in every reported subject and grade level. All-grade math proficiency was 64.6% versus the state's 44.9% (+19.7 points), reading was 67.9% versus 48.6% (+19.3 points), and science was 35.8% versus 25.5% (+10.3 points). Fourth grade was the brightest spot: 79.6% proficient in math and 74.0% in reading, the largest grade-level margins in the data at +24.4 and +25.2 points above state.
A few items are worth watching. Fifth grade math proficiency was 45.3%, only 3.4 points above the state average and well below the school's fourth grade math score. Science slipped from 47.37% to 35.8% year over year, while math and reading each declined about 3 points. The school's lead over its district also narrowed: in 2024–2025 it was above the district by roughly 11.6 points in math and 4.8 in reading; in 2025–2026 those edges shrank to +3.6 points in math, +1.8 in reading, and −3.7 in science. Context matters too: 30.85% of students qualified for free or reduced lunch, and the student/teacher ratio was 12.3 to 1. Even with these fluctuations, Caledonia Elementary remains comfortably above state averages in every reported subject.
