In this report, we clarified the structure and the characteristics of Life-Design Study that is being offered as a high school technical education. We also explained the content of a Life-Design Study. Our findings are summarized as follows; 1. Large differences in the number of credits earned in each course or type are noted among various high schools. In particular, credits on welfare, and home and life courses have decreased. 2. Differences in credits in each area in the technical subject are due to the variation of the subjects selected by each school. These subjects reflect the specialty and characteristics of the course. 3. A Life-Design Study contains the basic subjects that are taken by 1st to 3rd-year high school students. 4. Both the common subjects and the common fundamental subjects are included as basic subjects in Home-Economics, Life-Design Study and other related courses. 5. A Life-Design Study included mainly the basics of the fashion design as well as food, clothes, and home designing.
