Pre-youth academy training starts at 12 years old. Fifty per cent of the players at the club's Youth Academy have come through the club's pre-youth academy training structure.

The activities connected to the pre-youth academy were transferred to the club's Société Anonyme Sportive Professionnelle (SASP) in December 2019.

That change, which encompasses both the sporting aspects and the education of the U12-U15 players, marked a major step in the search for excellence and coherence in the Gym's grassroots project, and reinforced the link between each level of the club as well as facilitating the development of young Aiglons.
