In order to compare the behavioral-related dimension of performance on co-op and non-coop students, we used one cohort of co-op students with 4 months of experience (N=547), and one cohort of non-co-op students (N=617) with 4 months of experience as detailed in Table 1. Non-co-op students were asked whether they had 4 months of work-experience or not. Because the sample of non-co-op was too small, we did not separate the samples of non-coop students with regard to the year of study.
