About Orinda Academy

Orinda Academy serves 59 high school students in grades 9 through 12 with an exceptionally small student-teacher ratio of 5.2 to 1, allowing for highly individualized attention with its 11 full-time equivalent teachers. This regular public school has earned a strong 9.0 out of 10 rating from MySchoolScout and ranks 756th out of 1,790 California high schools, placing it in the 58th percentile statewide. The intimate school environment provides students with personalized learning opportunities that would be difficult to achieve in larger traditional high schools.

With fewer than 60 students total, each student likely receives significant individual guidance and support from faculty members. Orinda Academy is situated in an affluent community where 86% of residents hold bachelor's degrees or higher, and the median household income exceeds $250,000. This highly educated environment, with a poverty rate of just 2.1%, creates a supportive backdrop for student achievement.

The neighborhood's median home value of $1.7 million reflects the area's desirability and stability. The school operates within Orinda's large suburban setting in Contra Costa County, providing students access to the cultural and educational resources of the broader Bay Area while maintaining the close-knit community feel that characterizes this prestigious Northern California town.

What Parents Should Know

With an enrollment of 59 students, Orinda Academy is a smaller school where families often find a close-knit community atmosphere. Smaller settings can mean more individual attention from teachers and staff, though they may offer fewer extracurricular options than larger schools.

With a student-teacher ratio of 5.2:1, Orinda Academy offers a notably low ratio compared to the national average. This typically means smaller class sizes and more opportunities for one-on-one interaction between students and teachers.

As a private school, Orinda Academy operates independently from the local public school district. Families considering this school should inquire about tuition costs, financial aid availability, and the admissions process. Private schools are not required to follow the same curriculum standards as public schools, which can be either an advantage or a consideration depending on your priorities.
