„In all 33 countries that participated in the Survey of Adult Skills (PIAAC), adults with more-educated parents were considerably more likely to complete tertiary education than adults with less-educated parents. On average across the countries that participated in the survey, adults with at least one tertiary-educated parent were 11 times more likely to complete tertiary education than adults whose parents had not completed upper secondary school.“
