It is well known that non-cognitive skills are an important determinant of success in life. However, their returns are not simple to measure and, as a result, relatively few studies have dealt with this empirical question. We consider sports participation while at school as one way of improving or signalling the individual’s non-cognitive skills endowment. We use four waves of Add Health data to study how sports participation by schoolchildren translates into labour-market success. We specifically test the hypotheses that participation in different types of sports at school leads to, ceteris paribus, very different types of jobs and labour-market insertion in general when adult. We take seriously the issue of endogeneity of sporting activities in order to tease out a causal relationship between childhood sporting activity and adult labour market success. As such, we contribute to the literature on the returns to non-cognitive skills. JEL Codes: J24/J28, L83, I2
