This research analyzed the reports on Free Semester System of 42 pilot schools, which do not have any assessment, in order to inspect the new ways of instructions and educational activities. The results are as follows; First, most of the basic subjects instructions on common courses were student-centered activities. Second, career exploration activities were diversified and enhanced. Third, optional courses provided various activities which fitted students’ interests and needs. Fourth, all of the educational necessities were provided for the pilot schools by the local community. However, Free Semester System’s new curriculum causes some confusion in the operation of educational plans, not only for first grade students but also second and third grade students. nbalanced new educational experiences among Free Semester System students and other grade students cause a sense of incongruity and alienation. In addition, career exploration activities put too much emphasis on intellectual exploration, career-test and career-counselling, and career related experience. Finally, optional courses programs were often redundant and required organization. uggestions to solve these problems are as follows; First, School staffs should build the school curriculum together from planning to management in order to decrease the gap between Free Semester System and general semester system. Second, the positive effect of Free Semester System should be applied to other grades to solve the sense of incongruity and to increase the quality of education. Third, career exploration activities need to be balanced by increasing the learning of vocational ethics. Fourth, optional courses have to be re-arranged to be more systematic. If additional research is conducted in accordance with the suggestions made by this research, Free Semester System will regain the authentic educational role of middle school, which is different from that of junior high school, and will play a role as the bridge of lementary school’s basic education and high school’s career-based education.
