Nationally, the movement remains limited in scale. Forty-nine high schools, or 1.3% of the 3,700 in the country, were blocked on Tuesday morning, the Ministry of Education reported.
Outside Gaston-Bachelard high school, a student threw a bottle of gasoline at the elected official, who was trying to intervene to get classes to resume. She was struck in the torso by a closed, full bottle.
According to the USL, these tensions"reflect the lack of a response from the executive, the consequences of which fall on Education staff.".
At 9:30 a.m., the ministry specified that no disruption had been reported in three-quarters of the departments.
In addition, 1.6% of teachers were on strike, mainly in secondary education, according to the same source.
The marches nevertheless drew notable crowds in several cities. In Toulouse, 3,500 people, including many young people, demonstrated in the city center, according to the prefecture.
In Rennes, a very young procession walked calmly for two hours. Three hundred meters from the destination, police blocked the demonstrators' advance.
A concert by the singer Ali, a local figure, was then improvised, followed by dances and intergenerational Breton circle dances.
The atmosphere was more tense in Aix-en-Provence. An arson fire, according to the region, partially ravaged the interior of Émile-Zola high school, which has been regularly blocked since the start of the high-school student movement.
The school remained closed all day, the education authority said.
The mobilization is part of a standoff over Parcoursup. On Monday, the vast majority of youth organizations and the education inter-union left the first meeting of the reform committee.
They denounced the presence of representatives of the far right and of employers, and criticized the lack of new responses from the government.
Two weeks ago, the government announced a gradual transformation of Parcoursup starting in 2027, ahead of a complete replacement in 2028.
