The competence of collaborative learning and the teamwork effectiveness constitute a basic and key competence in higher education. Included in the syllabus of several degrees in the field of social sciences, the collaborative competence is especially relevant for educational students, who are trained to become teachers (in pre and primary education), since teamwork is an important part of their professional role. Several are the dimensions for the analysis of this competence, although there are three dimensions repeated in different studies, also included in some international reports on teaching competences: (1) communication and support (ask and offer help), (2) developing/monitoring of collaborative roles, (3) collaborative knowledge creation (participation and interdependence). From these three dimensions, an assessment tool (rubric) was created, considering the whole process, the planning the task, the regulation of the performance and the final evaluation. In order to obtain an index of the effectiveness of the process, a number of activities were asked to students for being analyzed in the different groups (dynamics, work methodology, involvement, participation, interaction, commitment, responsibility, contribution, roles, inclusion, relevance, attitude, climate, communication, etc.). The paper concludes with the importance of self-assessment as a way of self-regulation in teamwork, emphasizing learning and its impact on higher education and professional development in future teachers. According to this, potential feedbacks and forwards are immersed in the evaluation processes that can help students training in the collaborative learning competence.
