Up to 500 schools across France will be partially or completely closed on Monday following days of student protests and clashes with riot police.
French Education Minister Édouard Geffray said lessons would be suspended at between 400 and 500 high schools because security conditions had not been met.
Geffray said 24 schools had been burned or vandalised since the protests began last week.
Thousands of students have taken part in demonstrations in Paris and other cities, including Montpellier, Nantes and Marseille.
The protesters are demanding more teachers, improved resources, better learning conditions and repairs to run-down school buildings.
French Justice Minister Gérald Darmanin said 735 of the country’s 3,700 schools had been affected in some way by violent protests as of Friday.
Geffray said the number affected on Monday could be similar, but added that authorities expected a gradual return to classes.
He also alleged that far-left activists had infiltrated the student movement and contributed to violent incidents, posing risks to students and education workers.
According to the minister, 78 education staff members had been injured during the protests.
French Interior Minister Laurent Nuñez said 1,747 people were arrested on Friday, while AFP reported that more than 5,000 people had been arrested since the protests began, about 85% of them minors.
Protest organisers have called for further demonstrations on Tuesday, accusing the government of failing to introduce concrete measures to address their concerns.
Prime Minister Sébastien Lecornu said the government was taking steps to address problems affecting students and education workers.
The measures include keeping classes running, improving school facilities, reorganising school schedules and making the university admissions system more transparent.
Lecornu also said the government was accelerating work on a proposed “vandal-pays” law, which would require those responsible for property damage to bear the cost of repairs.
