The aim of this research was to analyze the relevance of parents', teachers' and peers' opinions on vocational guidance and career planning in Italian students. A total of 634 participants were asked to fill in self-report questionnaires in order to investigate: (1) the correspondence between students' choice and parents' job and Self-Directed Search test results; (2) how much attention students paid to adult and peer suggestions at the moment of choosing their studies; (3) how much they are able to find for themselves the information needed to make a decision and their tendency to attribute to themselves and their commitment to the pursuit of their aspirations. Results show less coherence between parents' job and children's choice and Self-Directed Search test results. The students do not seem interested in adults' opinions and they do not seem to have the ability to make a decision using the relevant information obtained. These results highlight the importance of increasing experts' support and to help students achieve greater coherence among attitudes, interests, competences and social requirements.
