Students that could not be interviewed in school, were individually followed-up and interviewed via phone, mail or web. Numbers of this group are thus labeled in the second column as "outside" of school.
This group is very large in the German context due to some specificities of the German educational system: schools of the lower secondary track usually do not offer a 10th grade.
