Oak Grove’s high school curriculum is designed to provide the knowledge and skills that students will need to succeed in college and in life. Oak Grove’s graduation requirements in the core subjects of English, social studies, mathematics, science, and Spanish exceed those of most schools as well as the admission requirements for University of California campuses and other selective colleges across the country.

In addition to core subjects, all students select from a range of yearlong concentrations in visual and performing arts. At the end of each semester students enthusiastically contribute to the High School Showcase, where classrooms become galleries for ceramics, photography and painting, and music students perform live for family, friends, and the community. High School students interested in theater may elect to take Drama in the spring semester. Productions are staged at Theater 150 in the town of Ojai.

Daily Advisory Class is an important part of the overall curriculum. Each grade level has an Advisory Class with a dedicated teacher who acts as advisor and advocate for the students. Classes include relevant curriculum by grade level and offer opportunities to explore a broad spectrum of subjects including psychology, philosophy, culture, interpersonal relationship, and the nature of the human condition.  The 11th and 12th grade Advisory Classes also include some standardized test preparation and college advising.

Learning Extras: Each January regular afternoon classes give way to Winterm Projects for two weeks. During this time teachers offer a range of intensive mini-projects which vary according to student interest. Past Winterm Projects have included: Voluntary Simplicity, Green Building, Sound Engineering, Sewing, Woodwork, Jewelry Making, Film-making, and Permaculture.

Beyond their academic studies students participate in a full range of camping trips, community service opportunities, sports teams, clubs, and student council social activities.

At mid-semester student/parent/teacher conferences are held to discuss student progress. At the end of each semester letter grades with narrative assessments are reported.
