Hundreds of French lycées have been barricaded by teenagers in the biggest youth protest movement in decades. Students are forcing school closures and clashing with police over a set of grievances that are, by the government's own admission, legitimate: crumbling buildings, overcrowded classrooms, unreplaced absent teachers, and a system that segregates children by income and postcode. The prime minister has promised to address complaints on class sizes, long hours, dilapidated buildings, and teacher provisions. The OECD's own data makes the structural case plainly. France spends 28% more than the OECD average on upper secondary education, yet a child born in a deprived French neighbourhood has less chance of escaping their socioeconomic background than in most other developed nations. The spending is real; the returns are not reaching the students who need them most. Éric Charbonnier, an OECD education analyst, confirmed a marked gap between the most advantaged and disadvantaged students, noting that disadvantaged students are typically concentrated in disadvantaged schools — compounding the problem through higher teacher absenteeism and lower quality of learning delivered. The physical infrastructure tells its own story. Videos from students and teachers show leaks pouring into buckets during lessons, rats, holes in walls and ceilings, broken toilets, and classrooms hitting 35°C during last year's heatwaves. Thousands of schools at all levels need repair, many dating to 1960s construction. French regions are responsible for high school building upkeep but have demanded higher budgets from the central government. A senate report has advised that billions are needed in coming years for renovation and climate adaptation. Class sizes in France average 29 students per language lesson versus 26 across the OECD, but that average conceals sharp urban-rural divergence. Teachers and students in Paris and its suburbs describe classes of 36 or more. School days run from 8am to 6pm, with more instructional hours than most OECD countries crammed into just 36 weeks — fewer than the OECD average. Timetable chaos following baccalaureate reforms that increased subject-combination choice has created long gaps during the day, extending the total hours students spend on site without proportionally increasing learning time. Teacher absence is the sharpest equity failure. The education ministry acknowledges that roughly 10% of teaching hours across the year go undelivered. The union SNES-FSU estimated that more than half of all public middle and high schools started the September term lacking at least one teacher. In Seine-Saint-Denis, one of France's poorest areas, the parents' organisation FCPE estimated in 2019 that students missed 20% of their teaching hours due to unreplaced absent teachers — the equivalent of nearly one full year of missed schooling over a lifetime. The ministry could not confirm the figure but acknowledged the replacement rate was improving. Unions also flagged shortages of non-teaching staff, including school nurses and disability support. The spending paradox is the story's load-bearing fact. France's high expenditure on lycées is partly driven by costly vocational programmes that lack recognition even within France, while spending on pre-primary and primary education — where intervention has the highest returns — sits 11% below the OECD average. Teachers' mid- and late-career salaries are comparatively low, raising recruitment and retention questions. The money flows, but it flows to the wrong places in the wrong proportions, subsidising structural complexity rather than classroom quality. What the barricades represent is not a demand for more money in absolute terms — France already outspends its peers — but a demand for the money to reach the students and the buildings where the need is greatest. The government's concession that the complaints are legitimate is itself a data point: the system's own administrators know the allocation model is broken. The question is whether acknowledgment translates into redistribution or dissolves into another commission report.
