About Centennial School District R-1
Families in zip code 81138 (Jaroso, Colorado) are assigned to Centennial School District R-1 for public education through 12th. This overview covers the district’s funding levels, scale, rating, and what to expect from the enrollment process if you’re moving to or within this zip code.
Understanding the 1/10 Rating
Centennial School District R-1 has earned an overall SchoolDistrictFinder rating of 1/10, placing it in the low-rated tier. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in Colorado’s CMAS assessments (2025 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Colorado is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
⚠️ Small-district caveat. Centennial School District R-1 enrolls 193 students. A percentile rank drawn from so few test-takers is statistically unstable — it can move several points from one year to the next on normal variation alone, and a single class of students can swing it. Treat this rating as a rough signal rather than a precise ranking, and look at the school-level detail below before drawing conclusions.
Centennial School District R-1 holds a low overall rating, with reading and math proficiency among the lowest in Colorado on state assessments. Test results reflect many factors beyond the classroom, including community and economic conditions; a low score is a signal to research carefully, not a verdict on any individual school or teacher. Families in this area should research all available alternatives: inter-district transfers, charter schools, and magnet programs. Contact the district directly to understand exactly what programs are available at your assigned school.
