The purpose of this study is to explore the relationships between mismatch and maturity of career hopes of elementary and middle school parents and their children by using the current status of career education conducted by Korea Vocational Competency Development Institute. This study examines the cases of mismatches between parents and students desired career paths through the questions where students are asked about their career hopes in the three-year questionnaire. In addition, by analyzing the specificity of the 2017 questionnaire, we analyzed the average difference when the students perceived that a mismatch occurred but in actuality, did not. As a result, the career maturity of the students who answered that no mismatch occurred was statistically high, and the average of students who answered that parents and career hopes did not match was what is the parent s career hope? /I don t know. As a result of analyzing the 2017 questionnaire, if the students believe that no mismatch occurred, there is also no statistically significant difference in students career maturity. This enabled them to see that their children had a higher career maturity when they felt that they acknowledged their careers, regardless of whether they actually admitted their careers, and used a policy that would strengthen the parent-child relationship. I suggest that they should improve their career maturity.
