Highly educated parents can also use their social capital to promote their children’s development. A cohesive social network of well-educated individuals socializes children to expect that they too will attain high levels of academic success. It can also transmit cultural capital by teaching children the specific behaviors, patterns of speech, and cultural references that are valued by the educational and professional elite.
In most studies, parental education has been identified as the single strongest correlate of children’s success in school, the number of years they attend school, and their success later in life. Because parental education influences children’s learning both directly and through the choice of a school, we do not know how much of the correlation can be attributed to direct impact and how much to school-related factors. Teasing out the distinct causal impact of parental education is tricky, but given the strong association between parental education and student achievement in every industrialized society, the direct impact is undoubtedly substantial. Furthermore, quasi-experimental strategies have found positive effects of parental education on children’s outcomes. For instance, one study of Korean children adopted into American families shows that the adoptive mother’s education level is significantly associated with the child’s educational attainment.
