Best Public Schools in Zip Code 81623

Zip code 81623 contains 7 schools serving roughly 1,707 students across Carbondale and Marble, Colorado, including elementary, middle, high, and alternative schools, most of which belong to the Roaring Fork School District No. Re-1, with Ross Montessori School overseen by the State Charter School Institute and Marble Charter School belonging to the Gunnison Watershed School District Re1J.

Academic performance varies widely across the area. Marble Charter School posts the strongest test scores, with 71.4% proficiency in both English Language Arts and Math, well above state averages, though its tiny enrollment of 34 students means year-to-year swings are dramatic. Carbondale Community Charter School is the most well-rounded option, combining strong scores (54.3% ELA, 42.6% Math), the lowest chronic absenteeism in the area at 13.9%, and an excellent 10.9:1 student-teacher ratio. Roaring Fork High School is the strongest secondary school, exceeding state averages in SAT Math, Science, and 9th-grade Reading/Writing, with a low 1.3% dropout rate. By contrast, Crystal River Elementary School struggles, ranking in the 37th percentile with 3rd-grade ELA proficiency at just 23.1%. Bridges serves a high-needs population with an 87.9% chronic absenteeism rate and 24.7% dropout rate, indicating students requiring intensive support.

Several patterns stand out. Charter schools tend to lead academically, though Ross Montessori School sits near state averages, showing charter status alone does not guarantee results. Chronic absenteeism does not always correlate with low scores: Marble Charter has high absenteeism but top scores, while Carbondale Community Charter has both low absenteeism and strong performance. Carbondale Middle School shows notable strengths in 8th-grade Math and Science despite average overall scores. Poverty is a factor but not destiny: Carbondale Community Charter School posts strong results with 37% free/reduced lunch eligibility, while Ross Montessori has similar poverty but weaker outcomes. For parents, Carbondale Community Charter School is the standout overall choice, Marble Charter is an academic outlier with caveats around size, and Roaring Fork High School is the clear top secondary option.
