Based on Family Social Capital Theory, this study uses secondary data analysis and structural equation modeling to explore the influence of family on independent living of high school students with disabilities after graduating from school. Using the data from Special Needs Education Longitudinal Study (SNELS), this research found that family social economic status positively effects family social capital, and thus improve independent living of high school students with disabilities after their graduation. However, for the family who lacks social capital, higher social economic status of family is not conducive to independent living of high school students with disabilities. Therefore, this research suggests that related policies and practice should pay more attention to the accumulation of family social capital and the impact of family on independent living of individuals with disabilities.
