Work-integrated learning (WIL) responds to the labor market's requests by fostering students' competency acquisition and development through active methodologies and profession-oriented practices. This training system means that both academic and workplace tutors guide and supervise the student. The research goal was to identify the tutors' professional profiles in WIL. This study's qualitative methodology is based on data triangulation obtained by the Delphi method, focus groups and a literature review. The participants are international experts in WIL. The outcome of the research is a set of specific and transversal competencies and functions for both types of tutors who guide and supervise students throughout their learning process in a workplace-based university program. In conclusion, the results enabled the establishment of a basis on which to identify WIL professionals working in different territories, as well as create professional development training for such agents involved in this innovative system.
