Summary

Clayton Partnership School is an elementary school serving grades K-8 in Thornton, Colorado, with 441 students. Over the past 10 years, this public magnet school has consistently ranked in the bottom half of Colorado elementary schools, with a 1-star rating from SchoolDigger for most of that time period.

The school faces several significant challenges. It has relatively high dropout rates, ranging from 1.9% to 3.9% in recent years, and experiences high chronic absenteeism rates, reaching as high as 36.9%. Academically, Clayton Partnership School's performance on CMAS tests is consistently below the state and Mapleton School District No. 1 averages across all grade levels and subject areas. For example, in 2024-2025, only 24% of students were proficient or better in English Language Arts, compared to the state average of 44.8%. The school also has a very high percentage of students (over 80%) eligible for free or reduced-price lunch, indicating a high-poverty student population.

When comparing Clayton Partnership School to other nearby schools in the Mapleton School District No. 1 and the Adams 12 Five Star Schools district, it becomes clear that Clayton Partnership School is one of the lowest-performing schools in the area. The school's declining performance over the past 10 years, with a drop from a 2-star rating to a 1-star rating, suggests that it is facing significant challenges in terms of resources, staffing, and support for its students.
