Summary:
The three middle schools serving zip code 80550 in the Windsor/Severance area of Colorado — Windsor Middle School, Severance Middle School, and Windsor Charter Academy Middle School — together educate 1,850 students in grades 6–8. All three are part of Weld County Reorganized School District No. Re-4, a 4-star district ranked 19th out of 115 districts in Colorado.
Windsor Charter Academy Middle School is the clear standout. It ranks 90th out of 469 Colorado middle schools (81st percentile) and posts the highest proficiency rates in every subject: 62.9% in English language arts, 53.1% in math, and 42.0% in science — all above state averages. It also has the lowest chronic absenteeism (9.5%) and the lowest free/reduced lunch rate (16.7%), despite having the largest student–teacher ratio (17.2). Among the two traditional schools, Severance Middle School holds a better state ranking (202nd versus 224th) and outperforms Windsor Middle School in both ELA (41.8% vs. 38.7%) and math (32.9% vs. 30.5%), even while serving a higher-needs population (33.6% free/reduced lunch). Windsor Middle School, meanwhile, falls below district and state averages in reading and math.
The most concerning area-wide trend is a broad decline in proficiency. Windsor Charter Academy Middle School dropped 9.7 points in ELA and 8.4 points in math from the prior year, and Windsor Middle School fell about 6.6 and 6.9 points respectively, while Severance Middle School held steady in ELA. State rankings are shifting as well: Windsor Middle School has slid from 175th to 224th over three years, while Severance Middle School improved from 227th to 178th before settling at 202nd. For parents, a three-tier picture emerges: Windsor Charter Academy Middle School leads academically with minimal absenteeism, Severance Middle School is the most resilient traditional school, and Windsor Middle School, despite its large enrollment, faces the steepest academic challenges.
