Summary

Coast Union High is a very small public high school serving about 159 students in grades 9-12 in the coastal community of Cambria, part of the Coast Unified school district.

This school presents a complex picture for parents. On one hand, it boasts a perfect 100% graduation rate and a remarkably low student-to-teacher ratio of 10-to-1, thanks to very high per-student spending. On the other hand, its academic performance on state tests has been extremely volatile, with recent scores in English and Math dropping significantly below both state averages and those of the larger, nearby Morro Bay High. The school also reports a high rate of chronic student absenteeism, which can impact learning.

When compared to Morro Bay High in the neighboring San Luis Coastal Unified district, the differences are stark. While Coast Union spends more than twice per student and has smaller classes, Morro Bay High maintains more consistent and higher academic results with a lower chronic absenteeism rate. This contrast highlights that while Coast Union High successfully supports students to graduation, there are significant questions about the effectiveness of its resources in translating to stable academic achievement.
