Summary

Mountain High is a very small public high school serving grades 9-12 in the mountain community of Lake Arrowhead, CA, with an enrollment of just 44 students in the Rim of the World Unified district.

The school faces significant challenges, most critically an extremely high rate of chronic absenteeism at 94.8%, meaning nearly every student misses a large portion of school, which directly impacts learning. This is accompanied by a high dropout rate of 31.4% and a low graduation rate of 68.6%, with no students testing proficient in math last year. These metrics are far worse than state and district averages, and the school's low statewide ranking reflects these ongoing struggles.

These issues are particularly striking because Rim of the World High, located less than a quarter-mile away in the same district, performs much better across all areas, including attendance, graduation, and academics. While other high-need schools in the area like Sierra High and San Andreas High also face high absenteeism, Mountain High's outcomes are among the most severe, raising important questions about its specific model and effectiveness despite higher per-student spending.
