This presentation will share a good practice example of a how a Dual Career (DC) Development Environment (DCDE) facilitated student-athletes’ transition to a Scandinavian university. We designed the study as a mixed-methods intrinsic case study (Hodge & Sharp, 2016) with a convergent design (Creswell & Creswell, 2018), combining the holistic ecological and holistic developmental approaches (Henriksen & Stambulova, 2017; Wylleman, 2019) and considering DC balance (Stambulova et al., 2015) as the primary concern for support. Using the DC-Environment Success Factors (DC-ESF) working model (Henriksen et al., 2020) as our guide we explored the case through multiple sources of data. Semi-structured interviews, with nine student-athletes and four support providers, and document analysis were complemented with ten-months of quantitative monitoring of the student-athletes’ transition experiences (e.g., DC balance, demands and coping). Findings are summarized in an empirical version of the DC-ESF model which, for example, showed a challenging transition within a well-coordinated and supportive environment; student-athletes taking part in everyday activities infused by a flexible sport-study exchange and support providers emphasizing balance and targeting empowerment of the whole person. Student-athletes improved in sport and study and in their ability to balance their DC. They started to recognize that to develop optimally they needed to consider their needs across life domains. These findings, and more, will be situated as part of the specific bounded case to illustrate how a DCDE can support student-athletes in the process of striving for career excellence in sport and life, by balancing their DC.
