This paper addresses a return of experience relative to the combination of several innovative educational approaches (classic lecture, per peers, and flipped classroom) to teach industrial test to undergraduate students from Polytech Montpellier engineering school. The objectives of the course were technical and educational: acquiring industrial test competencies in a way, students were the protagonists of their learning and for some topics they were the contributors of their peers'. At the end of the course, the teacher marked the students' skills and asked them to evaluate the course educational approaches completing a dedicated form created based on the F2A Louvain University one [1] to provide an objective and classifiable feedback. The paper presents the analysis of all results, states about this original experience and the future trends.
