The present work aims to explore the knowledge that the students of the Master's Degree in Teaching at the University of La Laguna have about the functions of educational guidance and their role as teachers and tutors. To this end, this paper presents a review of the role of educational guidance in a Secondary Education center and the role of the tutor. Teachers' perception of the educational guidance and tutorial function, its importance and difficulties, and the evolution of initial training until reaching the current Master's degree is also presented. In addition, a mixed methodology is used, focused on a documentary analysis of the Title Verification and the teaching guides, a focus group interview, and a questionnaire on the self-perception of students of the competences in tutoring and educational guidance. The results show that students consider that the Master's program does not include sufficient training with respect to their tutoring and mentoring functions. Finally, the conclusion is reached that the students do not consider themselves prepared to exercise the tutorial function and proposals are suggested to improve this training.
