Summary

Six Rivers Charter High is a small, highly-rated public charter school serving about 106 students in grades 9-12 within the Northern Humboldt Union High district in Arcata, CA, that achieves strong academic results with notable efficiency.

The school stands out for its perfect 100% graduation rate and significantly above-average performance in English and Science compared to both the district and state. It serves a diverse student population effectively, historically excelling with students from lower socioeconomic backgrounds. Interestingly, it accomplishes this while spending considerably less per student than many nearby schools like McKinleyville High or Eureka Senior High, demonstrating strong cost-effectiveness. However, a key area of concern is a high rate of chronic student absenteeism, which is above the state average, even though students continue to perform well academically.

Within the local educational landscape, Six Rivers is a top performer, ranking alongside Northcoast Preparatory and Performing Arts Academy and ahead of comprehensive high schools like Arcata High. Its main relative weakness is in mathematics, where proficiency is closer to the state average, a common challenge among area schools. For families seeking a rigorous, college-preparatory environment with a strong track record of graduation and academic success in core subjects, Six Rivers presents a compelling option in the region.
