This article examined the implementation of an open and distance learning system at the Higher Teachers' Training College of Maroua. According to the perspective of Leclercq (2000), we described the components of this learning system based on its motives, objectives, principles, discourses, training programs and methodology, actors, target audience, structures, resources, ICTs used, challenges and perspectives. The analysis of these elements shows that beyond the intention to innovate and the efforts made regarding technological, human and financial resources, challenges remain at all the levels of the development of the project. However, the main perspective outlined here reveals that it is not necessary to have a "ready-to-wear" innovation or an imported one before implementing it in the African context.
