Mammoth Unified

Summary:

The Mammoth Unified school district in Mammoth Lakes serves about 1,100 students across four public schools: Mammoth Elementary, Mammoth Middle, Mammoth High, and the much smaller Sierra High (Continuation).

Among these, Mammoth High stands out as the district's strongest performer, with a very high graduation rate of 95.6% and the best English Language Arts scores. The district as a whole excels in science, outperforming the state average, and has a strong graduation rate. However, chronic absenteeism is higher than the state average across most schools, and math performance tends to decline in the higher grades compared to elementary levels.

For families, it's important to note that Sierra High (Continuation) serves a specific, very small population with different needs and resources. The district shows some year-to-year fluctuations in school rankings, but overall provides a solid education with particular strengths in getting students to graduation and in science instruction, while working on challenges like attendance and consistent math achievement.
