Stone Valley Middle School in Alamo versus private

We're currently at an Oakland public elementary school but will be moving to the Alamo area this summer.  We're trying to get a better feel for Stone Valley Middle School versus the private schools in that area.  Due to covid and the lack of onsite tours, it's been difficult to get a sense of the schools.  I am looking for a school that will motivate/challenge my child so they don't just cruise through middle school.
