Better than 7% of Colorado middle schools

Summary

Shadow Ridge Middle School is a public school in Thornton, CO, serving 632 students in grades 6-8 as part of the Adams 12 Five Star Schools district. The school is currently ranked in the 7th percentile statewide (436th out of 469 Colorado middle schools), placing it among the lowest-performing schools in the state with a 0-star rating.

Academically, the school is severely underperforming compared to both district and state averages. Only 17% of students are proficient in ELA, 10.9% in math, and 14.8% in 8th grade science—roughly 25 to 27 percentage points below state averages. These gaps appear early, with just 6.7% of 6th graders proficient in math. The school's chronic absenteeism rate of 37.9% means nearly 4 in 10 students are missing substantial instructional time. This attendance challenge contrasts sharply with nearby higher-performing schools like Westlake Middle School (23.8%) and Rocky Top Middle School (24.4%).

What makes this situation particularly concerning is that the school has shown a clear decade-long decline, falling from the 43rd percentile in 2016-2017 to the 7th percentile today. Poverty does not fully explain the performance gap—Prairie View Middle School has a nearly identical free/reduced lunch rate (58.9%) but scores 29.1% in ELA and 20.2% in math. More tellingly, Rodger Quist Middle School, located just 2.43 miles away, achieves 40.3% ELA and 30.1% math proficiency with lower chronic absenteeism. Even with a lower student-teacher ratio (16.3) than several higher-performing nearby schools, Shadow Ridge's outcomes demonstrate that attendance, instructional supports, and school climate require urgent attention.
