Success at baccalauréat level (equivalent to A-level) is far less common amongst children whose father has endured a period of long-term unemployment. The difference in this success rate is 20%. This difference is partly due to the fact that unemployment primarily concerns fathers with few qualifications, less able to help their children with their schoolwork. But parental unemployment also carries its own specific problem: it reduces the probability of obtaining the baccalauréat by 12%.
