About Sierra Grande School District R-30

Sierra Grande School District R-30 serves zip code 81123, covering Sierra Grande, Colorado with grades Pre-K – 12th. Whether you’re researching a move, evaluating a home purchase, or preparing to enroll a child, the sections below give you a complete picture of this district’s resources, size, and what its rating means for your family.

Funding and Resources

Public school districts in Colorado spend approximately $12,800 per student per year on average (state-level estimate; district-level figures vary), near the national average (U.S. average: $13,700/year). Near-average districts typically provide core academic programs with adequate staffing, though program breadth may be more limited than in higher-funded systems. Per-pupil spending directly affects teacher compensation, class sizes, elective course offerings, technology access, and the depth of student support services — making it one of the most meaningful structural indicators of district capacity.

District Scale and Program Breadth

With 1 schools, Sierra Grande School District R-30 operates as a small, community-focused district serving students from Pre-K – 12th. Small districts often benefit from tighter community cohesion, more personalized teacher-student relationships, and stronger parental involvement. The trade-off is narrower program variety: fewer elective courses, specialized tracks, or extracurricular options than larger systems offer.

Understanding the 2/10 Rating

Sierra Grande School District R-30 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.

Sierra Grande School District R-30 carries a below-average rating, with reading and math proficiency rates below typical Colorado benchmarks on state assessments. A below-average score reflects test performance relative to other districts — not necessarily teaching quality or school culture, and some of these districts have schools with strong communities and dedicated staff. Families should research specific school quality, visit in person, and ask about available programs. Also ask about open enrollment and magnet options that may offer alternatives to the default attendance-zone assignment.

Enrollment for Families in Zip Code 81123

Children in zip code 81123 are assigned to Sierra Grande School District R-30 for public school enrollment, covering grades Pre-K – 12th.

Typical enrollment documents include proof of residency (lease or deed plus a utility bill), your child’s birth certificate, current immunization records, and prior school records. If your child has an IEP or 504 plan, bring that documentation to enrollment — Colorado districts are required to continue services within a reasonable period. Fall enrollment windows typically open in late winter or early spring; contact the district for exact dates and required steps.
