Summary:
High Schools located in zip code 80835 consist of a single school, Simla High School, a small public high school in the rural community of Simla serving grades 9 through 12 with 101 students. It is part of Big Sandy School District No. 100J, which ranks 14th out of 115 Colorado districts and holds a 4-star rating. Because there is only one high school in this zip code, this overview is really a detailed profile of Simla High School and what families can expect.
Simla High School stands out most for its strong attendance, low dropout rate, and early high school literacy. The dropout rate is just 0.9%, compared to 1.6% statewide, and chronic absenteeism is 13.7% versus 28.4% across Colorado. In 2025–2026, 82% of 9th graders and 78% of 10th graders scored proficient in Reading and Writing on the PSAT, well above state averages of 66% and 65%. Science results are also consistently above state levels, with 11th graders scoring 26.3% proficient in 2025–2026 versus 24.8% statewide. These achievements are especially notable because nearly half of the student body qualifies for free or reduced lunch, and the school’s 10.5-to-1 student-teacher ratio supports a high-touch learning environment.
The main area of concern is mathematics. In 2024–2025, only 16% of 10th graders were proficient in PSAT math, compared to 36% statewide, and 11th grade SAT math was 21% versus 32%. However, 2025–2026 showed improvement, with 10th grade math reaching 44% proficient, above the state’s 39%. These swings suggest an opportunity for more consistent math support. At the same time, Simla High School’s state rank has jumped from the 50th percentile in 2024–2025 to the 64th percentile in 2025–2026. With excellent attendance, strong district leadership, and clear literacy strengths, Simla High School is a small school trending in a positive direction, though families should pay attention to math performance.
