School social work is in its infancy in China, yet it has its special advantages in overcoming some increasingly evident social problems among contemporary college students, and it has become the necessary supplement to strengthening and promoting the ideological and political education in colleges and universities. According to the ownership of school social workers, this paper classifies them into three categories: engagement pattern out of school system, coexisting pattern within school system, and integration pattern within school system. After thorough SWOT analysis, the author puts forward that the integration pattern within school system is the best choice for the localization of school social work in China.
