The document summarizes a 9-year trilingual education pilot project in China that aimed to promote development and maintenance of the Kam language while also teaching Mandarin Chinese and English. Students were exposed to Kam, Chinese, and English in an instructional process that started with listening and speaking and added reading and writing over time. Evaluation results showed much higher academic achievement, language proficiency, and continuation to secondary school and beyond for students in the trilingual program compared to a control group receiving only Chinese instruction. The project demonstrated the ability of trilingual education to support minority language maintenance alongside development in the national language and a foreign language.
