Purpose: This study is to analyze the mediating effect of learning immersion in the relationship between NCS-based curriculum and learning satisfaction of the beauty related sector learners. By doing so, it aims to present basic data for revitalizing the beauty education industry and job security and protection by studying the effects of sub-factors of NCS-based curriculum on learning satisfaction of the beauty related sector learners. Method: This study collected 219 copies of answer sheets through an online survey method for learners of beauty related sector at NCS vocational training institutions. An empirical statistical analysis was performed using SPSS 25.0, PROCESS macro for SPSS. Multiple regression analysis and PROCESS macro model 4 were used. The significance of the mediating effect was confirmed through the bootstrap procedure. Results: As a result of conducting multiple regression analysis to verify the effect of the sub-factors of the NCS-based curriculum on learning satisfaction, it was found that educational content, educational method, and educational environment had a statistically significant positive effect on learning satisfaction. It was found that learning satisfaction was affected in the order of educational envi-ronment(β=.370, p<.001), educational method(β=.299, p<.001), and educational content(β=.142, p<.05). In addition, the partial mediating effect of learning immersion was judged to be statistically significant in the relationship between NCS-based curriculum and learning satisfaction. Conclusion: NCS-based curriculum was found to be a major factor in enhancing learning satisfaction in beauty related sector education, and it can be said that it indirectly affects learning satisfaction through learning immersion. Therefore, it is proposed to prepare an educational environment suitable for the characteristics of vocational training in the beauty related sector and develop suitable educational methods. In addition, if learning immersion is strengthened, it is expected to be of great help in achieving the goal.
