Stone Bridge School – a school of choice

As a public, independent charter school, SBS is considered a ‘school of choice,’ providing an alternative option to other public schools within the Napa Valley Unified School District.  

Schools of choice are considered non-boundary, which means that they do not use an address to determine priority.  Students are enrolled in Stone Bridge School on a space-available basis.  All students residing in California may apply for admission to SBS.  Students are selected randomly by lottery during our Open Enrollment period each year.

The school shall not discriminate against any student on the basis of race, religion, ethnicity, national origin, gender, sexual orientation, perceived orientation, home language, or disability, nor shall it charge tuition.


January 22, 2024 through 4:00pm PST on February 16, 2024

The initial open enrollment period closed on February 16, 2024. You may use the link below to apply for the 24/25 school year waitlist.
