Abstract
Adolescents' well-being is an important indicator of their successful development. Educational success is a likely but little investigated source for well-being. This paper will examine whether different components of educational success in the transition from lower-secondary to post-obligatory education affect young people's well-being in late adolescence. Based on the Swiss Survey of Children and Youth COCON, including a birth cohort of adolescents who were between 15 and 18 years old at the time points of data collection (2006-2009; N = 952), results of structural equation and multiple linear regression models show that educational success does indeed affect well-being at the age of 18.
