Many Interactive Learning Environments (ILE) produce assessment results. Norms exist to define how these results can be used, obtained and manipulated within ILE. AICC, certainly the most known, defines how to communicate assessment results and more widely, datas from a Learning Object (LO) to a Learning Management System (LMS). However, AICC and the other norms don't define what an assessment result has to look like. Moreover, assessment results are often semantically poor and expressed in a ILE-specific formalism. A common results model would improve the interoperability between ILE but also, if it is rich enough, clarify the meaning of assessment results. In this paper, such a common results model is introduced. At first its conceptual model is exposed, then its information model is described.
