Entry into secondary school corresponds approximately to entry into adolescence. This period, which often begins at the end of primary school, is a time of great upheaval for young people, bringing about major changes in their identity as well as physical, physiological, hormonal and emotional evolution. During this period, known as puberty, growth accelerates and the body gradually prepares itself for the acquisition of its reproductive function. While the physical changes are obvious, major metabolic, intellectual, social and emotional changes are also occurring at the same time. This process causes adolescents to question and define their identity, sexual and romantic attractions and relationships to the world.

Dress codes and their enforcement are often a sensitive issue that does not enjoy unanimous support among school teams. They can sometimes be a source of tension with parents and students.

In recent years, sexist and misogynistic ideas have become increasingly widespread on social media. Since the #MeToo movement in 2017, there has been an increase in such comments online, particularly through influencers who advocate a return to traditional gender roles and trivialize gender-based violence. Several European studies demonstrate the power and influence of sexist male influencers on social media, and the impact of this gender toxicity on young people in schools. This phenomenon is obviously not limited to Europe and is very present in Quebec.
