of 2,162 California High Schools

Better than 92% of California high schools

Summary

Las Lomas High is a top-tier, comprehensive public high school serving approximately 1,577 students in grades 9-12 within the affluent community of Walnut Creek and the highly-ranked Acalanes Union High district, where it consistently graduates over 96% of its students and performs in the 91st-95th percentiles statewide.

Within its own exceptional district, Las Lomas is a high performer that sits just behind its peers, Campolindo High and Acalanes High, in test scores, particularly in mathematics, and has a slightly higher rate of chronic student absenteeism. The school serves a more economically diverse student population than these immediate counterparts, and it shows notable strength in supporting several student subgroups to high levels of academic achievement. Compared to high schools in neighboring districts like Mt. Diablo Unified, such as College Park High or Northgate High, Las Lomas operates with significantly greater financial resources per student, which correlates with its strong outcomes.

Key takeaways for parents include the school's remarkable decade-long stability as a top California school, its effective support systems for a range of learners, and the stark resource and outcome disparities visible between nearby school districts. Areas for community attention include the recent rise in chronic absenteeism and the comparative gap in math proficiency, which is a common challenge across the region's high schools. Overall, Las Lomas represents a model of consistent excellence and is an interesting study in how school performance can vary even within an elite, high-achieving district.
