Summary

Sangre de Cristo Undivided High School is a small rural school in Mosca, Colorado, serving 146 students in grades 6 through 12 within the Sangre de Cristo School District No. Re-22J, a district rated 15th out of 115 in Colorado.

Sangre de Cristo stands out most in reading and science. In 2024-2025, 77% of students scored proficient on the PSAT10 Reading/Writing assessment, compared to 64% statewide. In 11th-grade science, 53.8% of students were proficient versus just 24.8% statewide. These results far exceed nearby schools such as Alamosa High School, which posted 41% on SAT Reading, and Monte Vista Senior High School, which posted only 17% in 11th-grade science. The school's student-teacher ratio of 9.3 is also much lower than Alamosa's 15.6, meaning smaller classes and more individual attention.

Math remains the clearest area for improvement, with only 19% of 11th graders proficient on SAT Math compared to 32% statewide. However, this mirrors a regional challenge — Sargent Senior High School also posted 19%, and Monte Vista Senior High School posted 16%. Chronic absenteeism affects about 27% of students, slightly below the state rate of 28.4% but above some nearby peers. The school currently ranks 131st out of 338 Colorado high schools with a 3-star rating. While small enrollment makes year-to-year scores volatile, Sangre de Cristo is clearly a strong performer in the San Luis Valley.
