Oakland School for the Arts (a.k.a. OSA) is an art high school located in Oakland, California. Once a cluster of portables and a gigantic tent in a parking lot (no, I am not kidding), the school moved into the newly-renovated Fox Theater in January 2008. It has gone through many changes, most notably the fluctuating dress code and student/teacher turnover rate.

Students there are required to participate in one of the school's arts emphasis. These include vocal music, instrumental music, visual arts, dance, literary arts, and arts management.
