Best High Schools in Zip Code 81321

Zip code 81321 in Cortez, Colorado, contains two high schools serving grades 9 through 12 — Montezuma-Cortez High School and Southwest Open Charter School — both belonging to the Montezuma-Cortez School District No. Re-1, with a combined enrollment of 729 students. Montezuma-Cortez High School is the larger traditional high school with 598 students, while Southwest Open Charter School serves 131 students. Montezuma-Cortez consistently outranks Southwest, finishing in the 21st percentile statewide in 2022–2023 compared to Southwest's 17th percentile, though both schools have seen their statewide percentile rankings decline since 2018–2019.

The most striking disparity between the two schools is in graduation outcomes. Montezuma-Cortez High School graduates 87.0% of its students, exceeding both the district average of 76.3% and the state average of 85.6%. By contrast, Southwest Open Charter School graduates only 34.3% of its students. Southwest also has the higher dropout rate at 7.6% versus 4.1% at Montezuma-Cortez, and chronic absenteeism affects 78.6% of Southwest students compared to 38.3% at Montezuma-Cortez. Both schools exceed the state dropout rate of 1.6% by significant margins.

Interestingly, Southwest Open Charter School has a much smaller student-teacher ratio of 12.5:1 compared to Montezuma-Cortez's 20.9:1, yet the larger school achieves dramatically better outcomes, suggesting that class size alone does not drive success. Both schools serve high-poverty populations, with 79.4% of Southwest students and 57.5% of Montezuma-Cortez students eligible for free or reduced lunch. The urgent area for intervention is clearly Southwest Open Charter School, where graduation rates are critically low and chronic absenteeism affects nearly eight in ten students, though Montezuma-Cortez also faces challenges with absenteeism and dropout rates well above state averages.
