Most approaches and theoretical and practical developments in this field revolve aroundfour main factors: feedback, democratization, alignment and relevance. This paper proposes the use of co-assessmentas a means of ensuring dialogue-based, democratic and fairer evaluations. With co-assessment, the responsibility isshared by the teacher and the students, who negotiate and agree on the appraisal of student tasks and, in this paper,also on the awarded mark. The aim of this study is to analyse the relationship between a series of jointly agreed marks,following the co-assessment of four tasks, and the marks that the teachers and students would each have individuallyawarded. Two teachers and 100 students participated in the study, which follows a correlational design and analysessignificant statistical differences. The results show a strong correlation between the jointly agreed marks and thoseassigned individually by the teacher, even though statistically significant differences were found between them.Conversely, no statistically significant differences were identified between the joint marks and the marks assignedindividually by the students. These results call for reflection on the real possibility of adapting shared grading methodsto students in university frameworks, where the repercussions of awarded marks go far beyond formative goals.
