West County Mandarin School (WCMS) is a Mandarin immersion, International Baccalaureate (IB) school located in Pinole, California (TK-5th grade campus) and El Sobrante, California (Middle School campus).  WCMS is the first Mandarin immersion public school in California to earn the acclaimed authorization as an IB school.  WCMS opened on August 21, 2017 with three kindergarten classes, and as of the 2025-2026 school year, it has grown to a full TK-8th school.

 The WCMS immersion model is one-way; students are not required to know any Mandarin prior to attending.  Even so, nearly a quarter of the students are intermediate to advanced speakers, and they enthusiastically help the novice students.

West County Mandarin School is the culmination of a collaboration between parents and community members and the West Contra Costa Unified School District.  It is the first Mandarin immersion school in the WCCUSD and the first whole school Mandarin immersion program in an East Bay Public School District.  Students from all over the District attend WCMS.  Our community is bonded by the desire to provide a quality, multilingual education that will prepare our students to become critical thinkers, leaders and problem solvers in our increasingly globally connected world.
