The prime purpose of this study is to find out whether there is any effect after a career development program has continuously been implemented. Unlike adults, this period of early juveniles is when their dominant process of personality types is actively developed. Accordingly, this study has attempted to verify the effect of career counseling programs, focusing on the area of the dominant process among the process types which are judged to be closely related to the effect of those programs in the personality types of juveniles.
For this, this study campared a experimental group and a control group. The result has shown the statistically meaningful difference between the two groups regarding career decision, attitude, and ability indicating the effect of the program. Furthermore, the covariance analysis has revealed that career attitude, decision, and ability varies statistically by dominant process type.
All the above-mentioned results considered, running a career development program for early juveniles can be said as an effective method for enhancing the level of their career maturity. In addition, early juveniles have shown different levels of career maturity depending on the development of their dominant process of personality.
