Intelligence is concerned about the increase in Islamized speech and practices as well as anti-Semitic acts committed by students. According to information from Europe 1, attacks on secularism in schools, middle schools and high schools in this Ile-de-France department have increased in recent months.

56 schools in the department have been the subject of incidents since last October. Several directors have recently been confronted with various incidents such as at the Croix Duny nursery school in Argenteuil where a third of the students' parents withdrew their children from class.
