Created in 2014 by Lionel Snow, the Children's Choir is open only to children in Year 5 to Year 9 who already have at least one year of musical experience. This group can perform alone, alongside other choirs, with the Orchestre de Paris or other guest orchestras. They are supervised by a team of four associate conductors, working closely with choir director Richard Wilberforce.
The choir's activities take place outside of school hours, in partnership with four conservatories:

• the conservatoire in Paris's 6th arrondissement / Choir director: Rémi Aguirre Zubiri,
• the conservatoire in Paris's 13th arrondissement / Choir director: Béatrice Warcollier,
• the conservatoire in Paris's 19th arrondissement / Choir director: Edwin Baudo,
• the CRR93 / Choir director: Evann Loget-Raymond.

The courses are organised in two parts, one part taught weekly by and at partner conservatories, and another part taught monthly by the Orchestre de Paris.
