In January 2016 the number of regions in France will be reduced from 22 to 13 as part of a major reform of local government.

In its response to the terror attacks in Paris in January the French government emphasised the importance of schools and the central role of secularism in fighting intolerance and extremism. Mediapart recently visited schools in the north of the French city of Amiens, an area which has recently seen riots and where the Moroccan-born education minister Najat Vallaud-Belkacem herself grew up and was educated. Here the issue of secularism divides teachers, parents and local help groups alike. “I have the impression that, faced with this debate, everyone is a bit lost,” says one teacher. Mediapart's education correspondent Lucie Delaporte reports from the city.
France's pupils and teachers have gone back to school this week in the annual ritual known as the 'rentrée scolaire'. Amid the usual hopes and expectations for the new school year, many teachers feel a growing sense of frustration. For despite the promise by President François Hollande to make education a priority and create 60,000 new teaching posts, many current staff feel their working conditions and pay have been overlooked. In some deprived areas, meanwhile, hard-pressed teachers have been voting with their feet, asking to be transferred to less challenging regions. Here Mediapart examines the situation in three of those vulnerable education authorities, who have been forced to take on thousands of trainee teachers to fill their classrooms this year. Thomas Saint-Cricq and Lucie Delaporte report.
