The Marin School of Arts and Technology (MSAT) was a small charter school in Marin County, California, that existed between 2003 and 2007. Located in the College of Marin's Indian Valley campus in Novato, California, it was operated by Envision Schools, an organization funded by the Bill and Melinda Gates Foundation. Conceived as a "small high school," the school's focus was on teaching a rigorous, project-based curriculum, using art and technology as tools for learning.
