This article presents a participatory evaluation project conducted between March 2022 and April 2023 at Artenso, a research centre in art and social engagement affiliated with the Cégep de Saint-Laurent in Montreal. The cultural mediation program named Parascol’arts – J’ai léz’arts à cœur, developed and delivered by the team of Diffusion Mordicus, a cultural organization located in Amqui (Bas-Saint-Lurent/Gaspésie), was analyzed to highlight and improve its structure, its social benefits as well as its cultural and territorial anchor. At the same time, Artenso deepened knowledge on participatory evaluation of cultural mediation practices.
