Six members of Korean association of sensory integration(KASI) participated the treatment course named C-course of japanese association for the study of sensory integrative dysfunction(JASSID) during Jul. 27$sim$Aug. 3, 2005. After the course, we investigated the education program of Japan and Korea and how it had been changed and developed. Through investigating JASSID with history for 23 years and KASI with history for 8 years, we find out that the common contents of sensory integration exist and the diversities of their own cultural and social contexts also exist. In korea, KASI would develop our own educational program and research based on having the close relationship with Japan and other former country developed education of sensory integration.
