Jefferson County School District No. R-1

Jefferson County School District No. R-1 is one of Colorado's largest public school systems, enrolling 74,251 students across 148 total schools. That scale gives families a wide range of options, from neighborhood elementaries to specialized programs spread throughout the district's communities west of Denver.

Performance across the district is consistently competitive. Of the 148 schools, 140 carry a ranking, and those schools average a score of 6.5 out of 10 — a solid baseline that reflects district-wide instructional investment rather than isolated pockets of achievement. The top-performing schools push well above that average, with several elementaries scoring in the upper 8s and demonstrating what the district can deliver at its best.

Welchester Elementary School leads the district with a score of 8.8 out of 10, placing it at the top of 140 ranked schools. Jefferson Academy Elementary and Bergen Valley Intermediate School each score 8.7, followed closely by Stony Creek Elementary at 8.6 and Hutchinson Elementary at 8.5. Five of the district's top schools land between 8.5 and 8.8 — a tight cluster that signals genuinely strong elementary options rather than a single outlier. Parents focused on elementary-age children have multiple high-performing choices to evaluate and compare.

For families considering Jefferson County R-1, the practical takeaway is that school quality varies meaningfully within the district, and the 1.3-point gap between the district average and the top school is worth factoring into school selection. Proximity to a high-scoring school matters here. Parents should cross-reference attendance boundaries early, since several of the top-ranked elementaries serve defined zones and may not be automatically available to all district residents. With 148 schools total and a strong upper tier concentrated at the elementary level, Jefferson County R-1 rewards parents who do the research — the data is there to make a well-informed decision.
