Summary

Chester Junior/Senior High is a small, rural school in Chester, California, serving about 124 students in grades 7 through 12 within the Plumas Unified district.

The school's standout strength is its 91.3% graduation rate, which is above the state average and dramatically higher than nearby Westwood High, despite both schools having similar below-average test scores in core subjects. This suggests Chester has effective systems to support students toward graduation. However, the school experiences significant year-to-year swings in its statewide ranking and other metrics, which can be common in small schools where a few students can greatly impact the data.

Chester faces challenges with chronic student absenteeism and low proficiency in math and science, though it generally performs better than Westwood High in these areas. It operates with a favorable student-teacher ratio and higher-than-average spending per student. Parents should note that while the school excels at graduating students, the volatility in annual performance and the academic proficiency scores indicate areas where the educational program could be strengthened for greater consistency and rigor.
