Best Public Schools in Zip Code 81428

Zip code 81428 (Paonia, Colorado) is home to exactly two elementary schools—Paonia K-8 and North Fork School of Integrated Studies—both part of Delta County Joint District No. 50 and sharing the same campus at 430 Box Elder. Paonia K-8 serves grades PK–8 (the only school in the zip covering 7th and 8th grade), while North Fork serves PK–6, and there is no standalone high school in the area. Both schools have majority low-income populations (58.3% and 51.8% free/reduced lunch respectively), yet they outperform the district and state in most core subjects, making this a notably high-performing, high-poverty cluster.

In the most recent comparable year (2024–2025), North Fork School of Integrated Studies edged out Paonia K-8 in both ELA (68.3% vs. 64.4% proficient) and math (45.7% vs. 42.9%), while maintaining a much healthier chronic absenteeism rate of 20.6% compared to Paonia K-8’s 39.5%. Paonia K-8’s attendance problem stands out sharply against the district (26.1%) and state (28.4%) averages and may help explain its declining statewide rank—from the 86th percentile in 2023–2024 to the 69th percentile in 2025–2026, with its star rating dropping from 4 to 3. That said, Paonia K-8 improved its math proficiency from 42.9% to 51.3% in 2025–2026 and still beats state averages in both ELA and math, but its 5th grade science score fell a dramatic 37 points year-over-year and 3rd grade ELA proficiency sits at just 25%.

For parents, the key takeaway is that both schools are strong academic options relative to Colorado averages, despite economic challenges and Paonia K-8’s attendance issues. North Fork School of Integrated Studies offers a smaller, tighter-knit environment with lower absenteeism and slightly better test scores, though its data is more limited. Paonia K-8 is the larger, more established school with a deeper track record, but its slipping ranking, weak 3rd grade literacy, and high chronic absenteeism are real concerns. Families should weigh North Fork’s strong day-to-day engagement against Paonia K-8’s broader grade span and more complete performance history.
