The project examines how and why inequality in education develops between students of different social origin. Broadly, it investigates how social, cultural and economic resources of students and their families influence educational outcomes. In particular, it studies how informed students and parents are about education, how they form beliefs about education based on information and resources, and how they subsequently make decisions about educational trajectories. A further focus of the project is on how these micro-level mechanisms differ across different national educational systems. The question, thereby, is if certain resources and mechanisms have a higher importance in some institutional settings than in others. Longitudinal panel data in different countries as well as register data are used to compare individual-level trajectories across educational systems.
