If the concept of learners profiles is now well known and treated in various ILE (Interactive Learning Environments), the taking into account of evolution in profiles do not benefit from the same advances. The subject of this paper is to define this notion and to show how it is taken into account in ILE researches. After a definition of the concept of evolutive learners profiles illustrated with examples, we show how this concept changes the models of our project, notably the evolution of PMDL profiles modeling language to PMDLe, that take into account the evolutivity of profiles. Then we present the consequences and benefits of these changes in the different modules of EPROFILEA environment that implement our models.
