  • SES was not measured directly. Instead, school type was used as a proxy. Schleswig-Holstein has a school system with 4 types of schools, and type of school is strongly associated with SES. The Hauptschule recruits pupils from low SES, the Realschule recruits students with mid SES, the Gymnasium pupils have a mid to high SES background, and the Gesamtschule is a mixed form.
