Summary:

ZIP code 93546 has three high schools serving grades 7–12: Mammoth High (grades 9–12), Jan Work Community (grades 7–12) and Sierra High (Continuation) (grades 10–12); together they enroll 350 students, with Mammoth accounting for 94%. The clearest concern across these schools is chronic absenteeism: in 2025–2026, rates ranged from 32% at Mammoth to 83% at Sierra, compared with 18% statewide.

Mammoth High stands out in the available academic results, though the results do not establish a top school across all three: in 2025–2026, Mammoth was 10 percentage points above California in English language arts and 5 points above in science, but 15 points below in math. Jan Work Community and Sierra High (Continuation) cannot be compared academically from these data: Jan Work’s test results are suppressed, and no test-score entries are supplied for Sierra. For attendance, Sierra is the clear bottom, at 83%—65 points above the state rate—followed by Jan Work at 54% (36 points above) and Mammoth at 32% (13 points above). Jan Work has the highest free/reduced lunch eligible share, 73% in 2024–2025, compared with 39% at Mammoth and 33% at Sierra.

Mammoth High’s results have moved in different directions: from 2024–2025 to 2025–2026, ELA fell 8 points, math fell 1 point and science rose 4 points; its state lead narrowed by 9 points in ELA, its math deficit widened by 2 points, and its science lead grew by 1 point. SchoolDigger gives Mammoth 3 stars and a 62nd-percentile ranking for 2025–2026 (805 of 2,137), down 7 percentile points from 2023–2024. School context also differs: 2024–2025 student–teacher ratios were 15.4 at Mammoth, 11.4 at Jan Work and 9.0 at Sierra; Sierra’s lower ratio occurs alongside its highest absenteeism, which is an observation rather than an explanation of results.
