The assessment of competences, within the accreditation activities and continuous improvement of the engineering programs, is a process that must be seen as a continuous and organized procedure. Thus, in the first semester of 2018, the measurement of Student Outcome 'd' was developed: 'To work in various teams and multidisciplinary environments', through a self-Assessment of the work teams of the Integrated Project course (PI in Spanish), to verify at what level of achievement this competence is being met. For this purpose, a rubric that was initially formalized by the board of experts was used, and it was applied in a practical way at the end of the course with the students of the PI course (95 students) to verify the scope of this competence as shown in the results obtained. The analysis of the rubric worked with the performance indicators shows a good correlation between the considered evaluation criteria.
