About Collège Saint-Justin
Collège Saint-Justin is a secondary school located in Levallois-Perret, in the Hauts-de-Seine department, in the Île-de-France region of France. It is part of a broader educational grouping that includes several levels of schooling, alongside an institution known as Sainte-Marie, reflecting an educational continuity designed across multiple stages. The school operates within the Catholic education system and functions under an association contract with the State, combining its own educational project with adherence to national curricula set by the Ministry of Education.
Its location in Levallois-Perret, an urban commune in the inner Paris suburbs, makes it a local school serving families from this area and its surroundings. The college enrolls students in the first cycle of secondary education, generally from the equivalent of sixth to ninth grade, within an environment intended to support learning and personal development. The institution focuses on delivering the core knowledge required by official curricula while placing particular emphasis on individual student support and community life within the school, in keeping with the values associated with Catholic education.
The positioning of Collège Saint-Justin is rooted in a long-standing local history connected to the presence of faith-based institutions in Levallois-Perret, and in a pedagogical organization coordinated with the associated Sainte-Marie primary school, thereby fostering continuity in students' educational paths from the early years through the end of middle school. The institution takes part in the local educational network, alongside other public and private institutions present in the commune, contributing to the diverse schooling options available to families in the Hauts-de-Seine department.
