School District No. Re-1 Valley

School District No. Re-1 Valley in northeastern Colorado serves 1,793 students across six schools: three elementary schools (Ayres Elementary School, Campbell Elementary School, and Caliche Elementary School), one middle school (Sterling Middle School), and two high schools (Sterling High School and Caliche Junior-Senior High School). The district holds a 2-star rating and ranks 73rd of 115 Colorado districts. Graduation rates are a clear strength — 94.4% compared to the state's 85.6% — and dropout rates are similarly impressive at 0.7% versus the state's 1.6%. However, academic proficiency across nearly every tested subject trails state averages.

The most striking pattern is the divide between the Caliche and Sterling schools. Caliche Junior-Senior High School is the district's academic leader, earning a 3-star rating and ranking 154th of 338 high schools. Its 9th graders posted PSAT math proficiency of 45% — more than double the district's 21% — and reading/writing proficiency of 70%, above the state average. The school also has the district's lowest chronic absenteeism rate (13.6%) and lowest student-to-teacher ratio (9.1). Caliche Elementary School has improved dramatically from a 0-star rating in 2023-2024 to a 2-star rating today, and it is the only school above district averages in both CMAS ELA and math. Sterling High School graduates students at a high 93.8% rate, but only 16-27% of its 9th graders meet math proficiency benchmarks. Sterling Middle School is the district's weakest tested school, with CMAS proficiency of 23.3% in ELA and 18.9% in math.

Campbell Elementary School deserves attention as a high-poverty overperformer: despite the highest free/reduced lunch rate (65.42%) and largest class sizes (17.7:1), it beats district averages in both CMAS subjects. Chronic absenteeism correlates strongly with performance — the highest-performing schools have the lowest absenteeism. Sterling High School has the highest rate at 27.3%, and improving attendance could be a key strategy. Ayres Elementary School, serving grades K-2, is a data blind spot with no test scores, but its 21.7% absenteeism rate suggests early patterns worth watching. Overall, this district keeps students in school well but struggles to move proficiency, especially math. The question for parents is whether the small-school advantages of Caliche — low ratios, strong attendance, close community ties — can be replicated in the larger Sterling schools.
