Children who are confident, responsible and believe in their capacity to affect the future are more likely to achieve high academic standards than those who are already smart. There is a strong impact of levels of cognitive, social and emotional skills in childhood on future development of these skills (Cunha and Heckman, 2008; Cunha, Heckman and Schennach, 2012). Moreover, these studies document that past levels of social and emotional skills play an important role in developing cognitive skills, although past cognitive skills have limited impact on future social and emotional skills.
