Résumé
In an IUT, "Institut Universitaire de Technologie"students are trained to become technicians after 2 years of study. Due to different reasons, the background level of incoming students is becoming lower and above all disparate. A special tutorage system introduced in 2014 to avoid resignations of first year bachelor students allows the first-year students to benefit from individual and collective support of second-year students in disciplines considered as difficult. During the first COVID confinement, three students, then in the first year, offered us a new concept of tutoring. As part of their tutored 2nd year project, they would like to write first-year exam corrections, but also organise collaborative work sessions for the 2nd year. We accepted this proposal, and student engagement was beyond our expectations. Spontaneously, as the teaching conditions returned to normal (100% face-to-face courses), a group of 3 students asked us if they could take part in this project again this year. The paper presents the organisation of the project in each of these two academic years, the commitment of the students to the project, and the feedback of their trainees. © 2022 IEEE.
