During academic course 2017-2018 the Comunica't methodology was created to help students to selflearn all the skills needed to master the areas of domain of the general student outcome "effective oral communication". After two academic years of implementation, the goal of this work is to analyse the degree of contribution of this methodology to development of the 'Effective Oral Communication" students' outcome of students that followed the methodology during the subject Audits of Food Safety and Quality Systems, belonging to the Master in Food Safety and Quality Management. To this end, at the beginning of the subject, students were asked to present a topic related to the subject and evaluated with respect to the six areas in which the project has defined the development of the outcome following a rubric. Then the methodology was presented, and at the end of the teaching period the procedure was repeated. Finally, marks obtained before and after the learning intervention were compared. Results showed that the methodology contributed in a great extent to improve the ordering of ideas in the presentation, the non-verbal communication and the design of the slides. Therefore, although there are fields where the methodology contributed to a lower percentage, it can be concluded that the methodology is very effective in improving effective oral communication student outcome.
