The Brazilian National Education Plan - PNE (Law nº 13.005 / 2014) determined that university extension activities must comprise at least 10% of the total curricular workload of undergraduate courses. The regulation of this rule occurred in 2018, through a Resolution CNE/CES nº 7 of the Ministry of Education (MEC). However, differently from what happens abroad, especially in developed countries, in which the interrelationship between teaching and extension is already quite advanced, in Brazil, this relationship does not occur with the same intensity. Besides, there are few studies on indicators and evaluation systems of service learning in Brazil. As a result of these findings, this article has the central objective of proposing a system for evaluating the integration of teaching and extension for Brazilian public universities. Thus, using a wide bibliographic and documentary survey in Brazil and the world, we propose an evaluation system that considers seven steps and four sets of indicators, in addition to some important points to consider in the analysis.
