The purpose of this study was to present directions for the development of special education by researching the characteristics of organizational cultures of special schools in South Korea. Integrated methodology combining quantitative and qualitative research methods was employed to carry out the research. The characteristics of organizational cultures in special schools were defined as follows: a tight life that's repeating itself day after day with disabled students, a double standard between solid lectures and prevention of safety accidents, difficulty with evaluation, a strong belief in the professionalism of each area of disability, symbiotic relationships with the assisting personnel to support the handicapped students, the double-sided tendency among the members of special schools, and the groupism-based sympathy in the organization of special schools.
