Summary:
Zip code 81091, a rural area in Weston, Colorado, is served by a single elementary school, Primero Elementary School, which educates 111 students in grades PK through 5 within the Primero Reorganized School District No. 2.
As the only elementary school in this zip code, Primero Elementary is automatically the standout option for local families, and it brings several notable strengths. In the 2024–2025 school year, the school earned an impressive 4-star state rating, ranking 251st out of 950 Colorado elementary schools—a significant jump from its 3-star rating the previous year. This placed it in the 74th percentile statewide, far outpacing its district, which received only 2 stars. Academically, Primero exceeded both district and state averages in math, with 42.6% of students proficient compared to 31.3% districtwide and 35.9% statewide. Fifth-grade science was also a clear strength, with 47.1% proficient versus 39.0% statewide. However, the most recent 2025–2026 test scores show a sharp decline, with ELA proficiency dropping from 42.6% to 25.0% and math falling from 42.6% to 30.0%. Third-grade math was particularly low at 17.6%, though with such a small student body, even a handful of students can cause large swings in these percentages.
Beyond test scores, families should note that chronic absenteeism affects about 1 in 4 students at Primero Elementary (24.8%), which is slightly above the district rate of 23.3% but below the statewide average of 28.4%. The school also serves a community where 36.04% of students qualify for free or reduced lunch, yet it still managed to exceed state averages in math and science in 2024–2025. Overall, Primero Elementary has shown a clear trajectory of improvement in its state ranking over the past three years, and while the recent score dip warrants attention, it may simply reflect normal year-to-year fluctuation in a small rural school rather than a long-term trend.
