The paper aimed to explore the professional functions of Indigenous Family Service Centers. For the purpose, the practical supervision experiences were collected and analyzed. It was found that, compared to Han people, indigenous peoples were inferior when accessing to resources and opportunities in education, employment, health and public welfare. In order to shorten these welfare resource gaps, Council of Indigenous Peoples had established 63 Indigenous Family Service Centers all over Taiwan to provide indigenous peoples with welfare services. Although the establishment and the current number of the Indigenous Family Service Center were still waiting for work, these centers had become the main place for the vulnerable indigenous family and people to receive professional services. According to the practical observation, it could be found that Indigenous Family Service Centers might face some professional difficulties: (1) the functions of the organizations which undertook the business of the center should be promoted; (2) the professional supervision function of the organization should be strengthened; (3) the professional manpower and abilities should be increased; and (4) the establishment of the center should be institutionalized.
