general high school students on career preparation behaviors and to examine mediating effects of career
attitude maturity in this relationship to help concrete and practical education plans for career education in
general high schools Purpose. In order to achieve this purpose, research questions were: First, whether the
level of career decision self-efficacy, career preparation behavior, and career attitude maturity differ
according to the grade level of general high school students; second, whether the career decision
self-efficacy, career preparation The relationship between career self-efficacy and career preparedness
behaviors is mediated by each sub-factor of career attitude maturity. The conclusions based on the results
analysis of the research problem are as follows. First, the level of career decision self - efficacy and career
preparation behavior was the highest in the third grade. When you are about to graduate, you will be more
interested in career and more prepared. Therefore, even if it is high 3, it should not neglect not only the
education focused on the SAT, but also the career education which can provide information about career
and job and increase self-efficacy. Second, the three variables of career decision self - efficacy, career
attitude maturity, and career preparation behaviors were statistically correlated. This suggests that when
designing career education for general high school students, it is necessary to design the curriculum in
detail so that they can improve their own abilities and beliefs about career and have a mature career
attitude according to career development stage. Third, there was a partial mediating effect between sub -
factors of career attitude maturity and career decision self - efficacy and career preparation behavior. A
program that can increase the level of determinism of career attitude maturity, which is a positive
mediating variable, can be used in the field of career education to help improve career preparation
behavior.

school students. In addition, it is meaningful to confirm that it is necessary to plan various and detailed
activities in career education by identifying mediating role of career attitude maturity.
