School Overview

Black Diamond Middle serves the eastern edge of Antioch, a working-class city in the far reaches of the East Bay where housing is more affordable but the commute into the Bay Area proper is real. Families looking for strong academics in this part of Contra Costa County will find the school's science scores a relative bright spot, though the overall numbers reflect the broader challenges the district faces. It's a school that may suit families who are invested in being active partners in their child's education and are drawn to the tight-knit, diverse communities that define this corner of the Bay.
