Trona Elementary

Public Grades K-6

5041^st

SchoolDigger Rank ?

of 5,857 California Elementary Schools

Better than 14% of California elementary schools

Summary

Trona Elementary is a small, rural K-6 school serving 147 students in the isolated community of Trona, California, within the Trona Joint Unified district.

Academic performance at the school is significantly below state averages, with only about 23% of students proficient in English and 22% in math. This places it well behind nearby schools in the Sierra Sands Unified district, such as Richmond Elementary and Gateway Elementary, where proficiency rates are roughly double. A major challenge is chronic absenteeism, with over 41% of students missing too much school, a rate higher than all nearby schools including Pierce Elementary.

Despite these challenges, Trona Elementary spends nearly $32,000 per student, which is almost double the amount spent by the comparison schools. The school's statewide ranking has declined over the past decade, and recent data shows particularly low performance rankings for its male students and students from low-income families. While the school serves a community with high economic need, the combination of extreme isolation, severe absenteeism, and academic results that lag behind even demographically similar schools indicates a complex set of obstacles for the district to address.
