This paper presents an approach to personalisation in e-learning. The concept of a Personalised Learning Policy (PLP) is introduced and its application in a Learning Management System (LMS) is detailed. Aiming to represent the criteria used in the system adaptation process, a data structure named Orientation Layer is proposed. The student current cognitive status is determined considering both the interactions between student and system and the aspects judged relevant to be observed. As a result, didactic contents and learning activities that match the pedagogical goals with the student?s preferences and skills are provided. That is, the LMS is endowed with a level of configurability and the system adaptive behaviour is consistent with the system users (i.e. teachers and students).
