The purpose of this study is to analyze existing core competencies from an educational perspective as a component of career experience activities and to propose a new competency framework. Current discussion of core competencies is based on a perspective that was appropriate in the context of the industrialization and democratization era. However, the future career competencies required for adolescents in this era ― that is, for adolescents who will live as leaders rather than followers, setting paths they have never been on ― need to be newly presented from the perspectives of creativity and sustainability. This study has attempted to make new proposals with educational branches such as teaching to solve the problems of survival from an economic point of view, learning for democratic communication from a social point of view, and active learning to practice autonomous learning from a political point of view. As a result, three career design competencies are proposed in this study: (a) a self-understanding-based learning ability that can be acquired through teaching, (b) an ability to live with various others, such as through fostering global citizenship, that can be formed through learning, and (c) public creativity and sustainability developed through active learning. This study recognizes the problem of there being a relatively insufficient concern regarding competency through active learning.
