Summary

Windsor Charter Academy Middle School is a public charter school in Windsor, Colorado, serving 395 students in grades 6–8 and belonging to the Weld County Reorganized School District No. Re-4. The school earned 4 stars and ranked 90th out of 469 schools statewide in 2025–2026—a strong result, though down from a 5-star performance the prior year.

Academically, Windsor Charter Academy far outpaces its district and state averages. In 2025–2026, 62.9% of students met or exceeded state standards in English Language Arts, compared to 49.0% for the district and 44.7% statewide; in math, 53.1% were proficient versus 42.4% district-wide and 37.3% statewide. Those numbers are especially striking when compared to nearby schools in the same district: Windsor Middle School posted 38.7% ELA and 30.5% math proficiency, while Severance Middle School posted 41.8% and 32.9%. Chronic absenteeism at Windsor Charter is also remarkably low at 9.5%, far below the district rate of 17.4% and the state rate of 28.4%.

The school's strengths extend to specific student groups. Hispanic students rank 11th out of 207 schools statewide for their subgroup, and low-income students placed 4th out of 244 in 2023–2024. Math proficiency also grows steadily from 42.2% in 6th grade to 65.2% in 8th grade, a sign of strong academic momentum. The school is not without areas to watch—Gifted and Talented students rank only in the mid-range statewide, and the recent dip in scores is worth monitoring. Even so, Windsor Charter remains one of the strongest middle schools in northern Colorado, comparing favorably to most peers, though Kinard Core Knowledge Middle School in Fort Collins still posts higher proficiency rates overall.
