Summary

American River Charter is a K-12 alternative school serving 263 students in Georgetown, CA, operating within the Black Oak Mine Unified School District.

The school's standout strength is its exceptional student attendance, with a chronic absenteeism rate of just 1.8%, which is dramatically lower than the state average and most nearby schools. However, this strong attendance does not fully translate to high academic achievement in core subjects; while the school outperforms its district and the state in Science, its proficiency in English and Math is lower than some comparable alternatives like Placer County Pathways Charter. Another notable feature is the high student-to-teacher ratio of 29.5 to 1, which is the highest among the local charter schools analyzed.

When compared to other schools, American River Charter presents a distinct profile. For instance, Sky Mountain Charter has similarly excellent attendance but stronger overall academic results, while Placer County Pathways Charter excels academically but has higher rates of absenteeism. Families may see this as a trade-off between a school culture that successfully promotes daily engagement and one that delivers higher test scores. The school's graduation rates have also shown significant variation from year to year, which is an important factor for parents to consider.
