Summary

Lassen High is a public high school serving grades 9-12 to about 816 students in Susanville, CA, as part of the Lassen Union High district, demonstrating a clear strength in guiding students to graduation despite facing academic challenges in core subjects.

The school's most notable achievement is its consistently high graduation rate, which has been over 90% for several years and exceeds both district and state averages, while its dropout rate remains lower. However, there is a significant concern in academic proficiency, particularly in mathematics and science, where scores fall well below state averages, even as performance in English Language Arts is closer to the state norm. This has contributed to a decline in the school's overall statewide ranking over the past decade. Additionally, chronic absenteeism has been rising and is now higher than the state average, which is an area the school is likely addressing.

Within its district, Lassen High serves as the primary comprehensive high school and performs markedly better across all key metrics compared to the district's alternative school, Credence High. While per-student spending has increased in recent years, the school is focused on improving academic outcomes, especially in math, and supporting all student groups equitably to ensure every graduate is prepared for their next steps after high school.
