    One important component of the Local Control and Accountability Plan (LCAP) process is the engagement of all stakeholders. All staff and parents/guardians, including those representing foster youth, homeless, and low-income and English learner communities, are consulted to provide feedback on the plan.  The district LCAP Advisory Committee is established to review and comment on the LCAP.
