Summary

Calaveras Unified Alternative-Sierra Hills Education Center is a K-12 alternative school serving 127 students in San Andreas, CA, within the larger Calaveras Unified district, and it stands out for its remarkable success in keeping students engaged and on track to graduate.

The school's greatest strengths are its perfect 100% graduation rate and a very low chronic absenteeism rate of just 6.4%, both of which dramatically outperform the district and state averages. This is particularly notable because the school serves a high-need population and achieves these results with lower per-student spending and a higher student-teacher ratio than many comparable schools. However, parents should be aware that academic proficiency, especially in mathematics, is a significant challenge, with only about 5% of students meeting state standards.

When compared to nearby alternative schools like Mountain Oaks and North Star Academy, Sierra Hills excels in graduation and attendance but lags in math scores. This creates an interesting profile: the school is exceptionally effective at supporting at-risk students to stay in school and graduate, suggesting a strong, supportive environment, but families may want to inquire about the specific academic support and math instruction available to help students reach their full potential.
