Due to the caution required to assess workplace performance through WIL programs (Hodges & Burchell, 2003; Hodges, Eames, & Coll, 2014; Stiggins, 1987), two instruments were used to test the hypotheses and compare the results. First, existing published and validated scales of the construct measure were used, after having been trial-tested with a small sample of respondents. All items were measured using a 5-point Likert-type scale from 1 (very little) to 5, (a great deal). Demographic variables were also collected (gender, length of experience) to determine if the respondent sample was representative of the population. Second, respondents (only co-op students) were asked on a 7-point Likert-type scale what score they received from their supervisor’s official appraisal (Employer Evaluation Form) on their last work-term, from 1 (outstanding) to 7 (unsatisfactory). These results have been compared with the database at the Career Centre of the University. Results fit with the database but could not be included in the research due to ethics.
