Reflecting upon their intercultural experiences, with a tool like the "Autobiography of intercultural encounters," may help adolescents become better interculturalists. This research investigates how the use of the Autobiography may allow adolescents develop intercultural competence (IC). Using Byram's framework on which this tool is designed, I analysed, both in terms of IC and participants' feelings, the Autobiographies of 20 adolescents participating in a Canadian linguistic student exchange. Analysis revealed a presence of elements of IC, but rather superficially. I propose some improvements so that adolescents engage in deeper reflection and become better interculturalists.
