The purpose of this study is to verify the mediating effect of Learning Flow in the relationship between Growth Mindset and Career Adaptability. Based on 203 response data collected from university students, hypotheses were analyzed using SPSS 26.0 and AMOS 26.0 programs. According to the result of this study, Growth Mindset had a direct positive (+) effect on Learning Flow (β=.403, p<.001), and Learning Flow also had a positive (+) effect on Career Adaptability (β=.393, p<.001). Also, in the relationship between Growth Mindset and Career Adaptability, Learning Flow showed a mediating effect. This means that in order for Growth Mindset to affect Career Adaptability, Learning Flow must be considered as essential. To this end, it suggests that it is important to build a Learning Flow along with cultivating a Growth Mindset.
