Part-time schedule, balanced workload and dynamic teaching : the entire programme is organized on a part-time basis to encourage students already involved in a professional situation to join. At the Institute of Labour Sciences, the teaching methods used have always made extensive use of many different kinds of training methods which put students firmly at the centre of their own learning, whilst taking account of theoretical and practical perspectives : individual and group work, reading, case studies, observations and empirical analyses etc.  This requires special attention to be paid to the workload since an excessive amount of work and examinations may prevent students from actively taking responsibility for their learning, especially if they are trying to combine their studies with a job. Each semester, the academic secretary, together with student representatives and the Institute office, has the task of coordinating the overall workload.
