The article investigates the utility of social capital for children's achievement, and asks if this utility interacts with family human capital and the quality of the parent-child relationship. Data stem from a Swedish cohort born in 1953 and consists of both survey and register data. We found that parents with more human capital tended to offer their children more social capital and that, when present, social capital was directly related to children's grades. The utility of social capital for acheivement did not depend on parents'human capital , but was enchanced when cobined with a very good parent-child relation.
