Why are French student protests over overcrowded schools escalating nationwide?

French student protests over overcrowded schools are escalating because the government's pledge of 3,000 extra supply teachers has failed to satisfy demonstrators [1]. The unrest, which began in late September, stems from chronic staff shortages, deteriorating facilities and overcrowded classrooms [3], and has spread from high schools to universities and workplaces with increasingly violent clashes between protesters and police [2]. The demonstrations have become a focal point in France's broader political divisions ahead of a presidential election, intensifying the conflict beyond the original educational grievances [1, 3].
