About Westside Preparatory

Westside Preparatory Charter School is located in Rio Linda, CA within the Twinrivers Unified School District. It is a charter school that serves over 400 students in grades 7-8. It is among the few middle schools in California to receive a distinguished school award.

Charter schools are public schools, but differ from traditional public schools in that they are independent and are operated by educators, parents, community leaders, educational entrepreneurs, or others. Funding for charter schools is based on designated local or state educational organizations. Those organizations are responsible for monitoring and assessing the quality and effectiveness of education, but permit the schools to operate outside of the traditional public school education system.

A school's Academic Performance Index (API) is a scale that ranges from 200 to 1000 and is calculated from the school's performance in the Standardized Testing and Reporting (STAR) Program. The state has set 800 as the API target for all schools to meet.
