In 30 years, the expected years of schooling for a student aged 15 have increased substantially (from 4.7 years to 6.5 years) before stabilising as a result of the drop in repeat years. The level of qualifications has risen significantly. When they finish their education, more than four out of ten young people have obtained a higher education diploma, compared with fewer than two out of ten 30 years ago. Fewer young people now leave school without a diploma, although this does still often happen, especially in deprived areas. Widespread access to the baccalauréat for students of all social backgrounds masks the very great variety of types of diploma held, with the vocational baccalauréats more often at the bottom of the social scale, while the general baccalauréats are at the top. These differences can also be seen in higher education where short courses of study (BTS-DUT) are more often undertaken by young people from less privileged backgrounds. For young people without a diploma, professional integration is difficult. Among those who entered the labour market at the end of 2010, almost half were unemployed.
