Even though there is no school exactly based on the theory of indigenous community-based curriculum in Taiwan, indigenous community-based education is still the promising policy from the context of indigenous school innovation. The aim of the case study was to explore the practice of the cultural curriculum in Lan-Yu High School in Orchid Island, and analyze from the perspective of community-based curriculum in order to understand the possibility and difficulty in the future development. The research began in August 2007 and ended in April 2008. The data collection methods were interview and observation. The research concluded that the school successfully developed diverse traditional cultural and culturally relevant curriculum, but the long-term and deep interaction between school and community were still instead of development. Moreover, the decolonial actions developed by the community did not stimulate the development of decolonial strategies in the school. The suggestions for the future include: creating the educational vision and the opportunity of cooperation with the community, continuing to develop immersion and culturally relevant curriculum and instruction, improving teachers’ multicultural literacy and the cooperation in curriculum development between elementary and high schools, and helping students understand the meanings of traditional culture in the modern society.</div>
