Offering an alternative college preparatory program, the school serves just over 600 students in grades nine through twelve.

The school was designed by architect Mario J. Ciampi to conform to the hillside[3] at the base of Milagra Ridge.

A 2002 modernization included a seismic upgrade, ocean facing classroom windows and a 350-seat theatre.

The class periods are 90 minutes each, so this gives the students time to work on projects, especially for English and History.

Oceana offers Advanced Placement courses in US History, Chemistry, US Government, Language and Composition, Literature, and Calculus AB.
