Summary:
The Blackduck Public School District in Minnesota serves 696 reported students across two schools: Blackduck Elementary, covering grades PK–6 with 412 students, and Blackduck Secondary, covering grades 7–12 with 284 students. There is no middle school or alternative school in the district. The district itself is ranked 337 of 458 schools, in the 26th percentile with 1 star — lower than both of its individual schools, which each hold 2 stars.
Comparing the two schools, Blackduck Elementary posts higher all-grade proficiency than Blackduck Secondary in every 2025–26 subject: Math 34.4% vs 23.5%, Reading 41.5% vs 25.2%, and Science 20.8% vs 18.4%. Elementary also beats the district average in all three subjects and has improved its rank percentile over three years (24 → 30 → 32). Secondary keeps a slightly higher rank percentile (36 vs 32) but is trending down (44 → 38 → 36) and trails the district and state in every subject. Both schools remain below state proficiency in Math, Reading, and Science. Notably, Elementary has the higher free/reduced lunch rate (60.92% vs 50%) and similar student/teacher ratios (14.6 vs 14.0), so Secondary's weaker results are not explained by those factors alone.
The clearest bright spots are Elementary 3rd grade Math at 60% (above the state's 57.9%), Elementary 5th grade Reading at 52.8%, and Secondary 11th grade Math at 31.3%. Concerns are concentrated at the secondary level: 10th grade Reading is 18.9% vs the state's 42.5%, 7th and 8th grade Math are far below state, Science swung from 41.67% in 2024–25 to 18.4% in 2025–26, and the dropout rate is 16.6% against a state rate of 4.2%, with graduation at 70.3% vs 84.9%. At Elementary, 3rd grade Math is strong but falls to 23.2% by 6th grade.
