In addressing the issue of interdisciplinary research in vocational guidance, twelve propositions important for understanding the vocational guidance process as joint, goal-directed action are presented. They address the encounter between client and counsellor leading to relational ethics, the relevance of everyday action theory and methods for the analysis of goal-directed processes as joint actions, projects, and careers. Research on the school-to-work transition illustrates this conceptualisation and analysis. Links to other disciplines concerned with vocational guidance are identified.
