Summary

Mountain Oaks is a public K-12 school in San Andreas, CA, serving 425 students under the Calaveras County Office of Education, and it stands out for its exceptional success in keeping students engaged and graduating them on time.

The school achieves remarkable results, including a 95.6% graduation rate and very low chronic absenteeism at 1.7%, despite having a much higher student-to-teacher ratio and lower spending per student than many other schools. While test scores in English and Math are areas for growth, the school is a particular standout in Science, where it outperforms the state average. Its consistent performance over several years, even during challenging times, shows a stable and effective learning environment.

When compared to nearby alternative schools like Calaveras Unified Alternative-Sierra Hills Education Center and North Star Academy, Mountain Oaks operates with notable efficiency, achieving strong outcomes with more modest resources. This makes it a compelling model of an alternative school that successfully supports its students toward graduation.
