Summary

The school is part of the Weld County Reorganized School District No. Re-4, which is ranked 18 out of 115 school districts in Colorado and has a 4-star rating from SchoolDigger.

Windsor Charter Academy Middle School consistently ranks among the top middle schools in Colorado, ranking 35th out of 469 schools in the 2024-2025 school year. The school's proficiency rates in CMAS English Language Arts and Math are significantly higher than the district and state averages across all grade levels, with a 72.6% ELA proficiency rate in 2024-2025 compared to 51.1% for the district and 44.8% for the state. The school's performance is particularly strong for Hispanic students, ranking 2nd out of 218 Colorado middle schools in ELA proficiency for this subgroup in 2024-2025, and it also performs well for students from low socioeconomic backgrounds, ranking 4th out of 244 Colorado middle schools in this category in 2023-2024.

Compared to other middle schools in the Weld County Reorganized School District No. Re-4, such as Severance Middle School and Windsor Middle School, Windsor Charter Academy Middle School outperforms them in academic proficiency. However, when compared to middle schools in the neighboring Poudre School District, such as Kinard Core Knowledge Middle School, Windsor Charter Academy Middle School performs well but is not as dominant. The school's increasing chronic absenteeism rate, reaching 27.7% in 2023-2024, is a potential area of concern that the school and district should address.
