This dissertation was designed to provide a comprehensive data-driven evaluation of a Chinese language Immersion Program (CIP) for the stakeholders. CIP was implemented in 2006 with a goal for students to become proficient in the Chinese language and develop increased cultural awareness while reaching at least the same level of academic achievement as their peers in non-immersion programs. Yet, CIP had never been fully evaluated. It was not known how and to what extent this CIP met the needs of immersion students.
