Competences are the most important career capital a university graduate can have. The objective of the paper is to determine which competences acquired at tourism degree programmes affect students' self-assessment regarding their own competitive advantage on the labour market. The data was collected during a nationwide diagnostic survey (N = 476) carried out at ten Polish universities among students finishing their tourism degree courses. Principal component analysis allowed us to identify a set of competences that have a significant impact on the students' perception of their chances of finding employment in the tourism industry. These are: ability to cope with challenges and stress; writing and speaking skills in a foreign language; public speaking; planning and implementation of subject-specific projects; ability to conduct subject-specific research and perseverance. The higher the assessment of each of the above, the more confident of their competitive advantage on the labour market the students were.
