Studies and policy reports worldwide argue that a modern employee must possess domain-general competencies to become employed. However, competency studies within upper-secondary initial vocational education and training are scarce. Therefore, this study aimed to scrutinise this topic and examined how the experienced learning environment contributes to student learning of competencies. Study participants were students in automotive engineering, mechanical and metal engineering, electrical and automation engineering and building service technology. The data were collected with an online questionnaire and analysed statistically using structural equation modelling. The research findings indicate firstly that eight competency domains could be recognised: work organisation, cooperation ability, professional attitude, problem solving, willingness to learn, active listening, empathy and assertiveness. Secondly, students' experienced learning environment was characterised by social support and recognition provided by educators, equal treatment between students and a positive climate for learning. Thirdly, the quality of the experienced learning environment contributed to learning of competencies. The research findings enhance the scientific and societal discussion about vocational graduate competencies and to what extent the experienced learning environment contributes to the learning of competencies.
