This study examined the level of collaboration between Francophone and Anglophone language teachers of 13- and 16- year-old Canadian students (N = 4,494) using data from the 2002 SAIP (School Achievement Indicators Program) of the Council of Ministers of Education of Canada. Among 32 factors, logistic regression identified six predictors of teacher collaboration, five of which were related to the school and one to the teacher. Results were discussed in light of a theoretical model designed to assess teacher collaboration. (Contains 1 table and 2 figures.)
