Summary

Mammoth High is a public high school serving about 330 students in grades 9-12 in the mountain community of Mammoth Lakes, part of the Mammoth Unified school district, and it generally performs above the state average.

The school has clear academic strengths, with students excelling in English Language Arts and graduating at rates well above the state average. However, math proficiency is a significant area for improvement, as scores lag behind both the district and state. A major concern is a sharp rise in chronic absenteeism, where the rate is now higher than the state average, which can impact overall learning. While per-student spending has increased notably in recent years, these specific challenges in math and attendance remain.

As the main comprehensive high school in the area, its profile is distinct from the much smaller nearby alternatives like Sierra High (Continuation) and Jan Work Community, which serve different student needs. Performance varies among different groups of students, with recent trends showing a particular need to support male students. The school's focus areas are likely on boosting math achievement, improving attendance, and ensuring all students have the support they need to succeed.
