„Young people whose parents do not have upper-secondary education are less likely to graduate themselves in all countries for which data are available. In Norway, however, only half of them achieve an upper-secondary degree within five years, compared to 56 % in Sweden and 57 % in Finland. The gap between the completion rates of the children of tertiary and lower-secondary educated parents is higher than in any other country for which data are available.“
