The aim of the paper is to illustrate how personal construct psychology and repertory grids (Kelly, 1955) can be used to produce cognitive maps, and to analyse psychological adjustment during the transition from university to employment. Cognitive maps are based on the principal component analysis of repertory grid data and provide a visual representation of the way in which the subjects see themselves in relation to other people, and in relation to their constructs. The cognitive maps produced by two graduates shortly after entry in employment and 6 months later are analysed and compared in order to identify trends of personal change. The case studies show that the analysis of the cognitive maps provides some valuable insights into the way in which graduates change their construction of themselves and of their work environment during the period of transition. The trends of change highlighted by the cognitive maps are discussed in the light of personal construct psychology concepts such as individuality, invalidation, fragmentation, and the mutual relationships between one's construction of oneself and one's construction of others.
