Summary

Clayton Partnership School is a K-8 school in Thornton, Colorado, serving 430 students in the Mapleton School District No. 1, a district that ranks in the bottom 10% of Colorado districts. The school itself ranks in the 26th percentile statewide (696th out of 943 schools), a steady improvement from its pandemic-era low but still below pre-2020 performance. About 78% of students qualify for free or reduced-price lunch, and chronic absenteeism runs at 37.9% — high, but lower than many neighboring schools.

Despite being in a lower-ranked district, Clayton outperforms all five nearby Adams 12 Five Star Schools, including North Star Elementary, North Mor Elementary, Thornton Elementary, Coronado Hills Elementary, and McElwain Elementary. In math, Clayton's 17.6% proficiency rate exceeds all of those schools, several of which sit at 10% or below. Within Mapleton, Clayton sits in the middle tier — behind Welby Community School of the Arts and Explore Pk-8, but ahead of Meadow Community School and Achieve Academy.

Clayton's most distinctive academic pattern is strong early-grade math: 35% of 3rd graders and 35.7% of 4th graders are proficient, near state averages, but by 8th grade that falls to 12.5%. English language arts shows a similar fade after 5th grade. The school has a history of strong outcomes for low-income students and currently earns strong marks for English Language Learner students. One concern is a persistent gender gap favoring boys, with girls ranking in the 9th percentile statewide. Science proficiency is at or above district levels, and with chronic absenteeism below most nearby schools, Clayton appears to be doing somewhat better than its demographics would suggest.
