The students' assessment regarding collaborative learning and workgroups is being reported as one of the main concerns in higher education. The increased technological evolution leads to adapting novel self and peer assessment methods to e-assessment. This paper reports the results of a study to evaluate students' opinion about their experience with an e-assessment tool, WebAVALIA, and its assessment criteria. The results indicate that students (N = 359) consider the tool fair, and it increases the productivity regarding work development. Kruskal-Wallis tests show that the students recently considered WebAVALIA fairer and more straightforward. Quickness and anonymity are also identified as tool advantages.
