This paper presents a consolidated report of the work of a group of experts investigating the possibility of organizing modern language teaching/learning in the form of a units/credits system, in order to allow an approach based on the individual motivations and capacities of the adult learner. In particular, three issues considered central to the introduction of a units/credits system are closely considered: (1) new forms of organization of linguistic content, (2) types of evaluation within a units/credits system, and (3) means of implementation of a units/credits system in the teaching/learning of modern languages in adult education. This report details the conclusions reached and the recommendations made for research and development work in each of these areas. (Author)
