The curriculum analysis of lighting design course in the Interior architecture departments in American universities reveals they share a major concern in the basic lighting theories, the sorts of light source and lighting equipment, daylighting, and interior lighting plav. The curriculum is usually composed of two semesters, the first semester being about lighting theory and simple project, while the second one abut more professional fields of design studio. The curriculum of lighting design at the Interior architecture departments in Korean colleges and universities usually consists of introductory courses in the field. Almost every institution allocated only one semester for the courses, and as the courses should cover the broad range within a short time, they were lacked in the required depth and systematic approach. The analysis also reveals the curriculum in Korea puts emphasis on the interior lighting equipment design, while disregarding the importance of daylighting. In comparison, American institutions have their curriculum focused upon the use of daylighting. The curriculum of lighting design courses in Korea, a major part of space rendering methods in the field of Interior Architecture, should be improved without delay. The courses should be included in the required subjects and the educational aims should be changed from offering a general understanding of the concepts to providing professional knowledge and skills, which would contribute to the competitiveness of the departments.
