After briefly presenting INCITE’s main research projects on LIS competences development and professional qualifications, this paper discusses this Association’s contribution to the redesign of LIS professional competences trajectories among adults in labour contexts, namely the movement from a pilot experience of constructing three LIS educational and vocational training frameworks, in 2004, to an active participation in the strategical task force led by the Institute of Employment and Vocational Training (IEFP) and the National Agency for Qualifications (ANQ), in 2007. This second task is expected to produce a National Qualifications Catalogue (CNQ), based on a constructive approach of lifelong learning capable of enriching what one may call a network of praxis and academia studies. This paper also proposes a reflection on the role of professional associations in prioritising lines of research and strategic positions capable of moulding the present and future of LIS competences and qualifications and of extending the range of possible choices in a framework adapted to the national level of competences asymmetries. Finally, it is pointed out that in Portugal the introduction of changes in LIS competences profiles and praxis are more effective in vocational training models than in educational models.
