University research for development requires ethical considerations. This research aims to understand the level of knowledge of ethics by the actors such as lecturers, researchers, and students at the undergraduate and graduate levels of the University of Parakou in Benin. For this purpose, an approach essentially based on a survey by electronic questionnaire was carried out among 95 persons. The results obtained reveal that research ethics is not well understood by a large proportion of university actors (50.5%), particularly students. The results show that men (51.59%) have a higher level of knowledge than women (28.42%) and that the higher the level of education, the greater the knowledge of ethical considerations. The type of the training institution determines the obligation of lecturers, researchers, and students to take into account the ethical rules related to their disciplines. It is the case especially in human health sciences.
