In the context of globalization, educational systems, from elementary to university, must take into account the increasingly complex realities they face, especially in terms of skills that teachers need to develop. In this respect, on both political and scientific levels, the importance of training on ethnocultural, religious and linguistic diversity comes up regularly. However, a portrait of teacher training in Québec universities has revealed an overall deficiency in this area (Larochelle-Audet, Borri-Anadon, McAndrew and Potvin, 2013). While a competency-based approach has prevailed since 2001 in teacher training, an inter-university work group has begun to address this gap by enriching the Department of Education’s professional frame of reference on teacher competencies. The work of the group, presented in this article, is based on a critical analysis of the department’s frame of reference, which reveals an absence of tangible considerations on ethnocultural diversity and the objectives of intercultural and inclusive teacher training. The members of the group developed two methods aiming to add intercultural and inclusive competencies to the reference framework: the first proposes the integration of 21 components into the 12 existing professional competencies, and the second favours the addition of a new intercultural and inclusive competency. Their operationalization entails some limitations and risks, which are the subject of a discussion in this article.
