It is necessary to provide disaster mitigation education at special needs schools, specifically for students with intellectual disabilities, because they are most likely to be vulnerable to sudden disasters. Therefore, in this school year, disaster mitigation education was introduced to sixth-grade students as a part of the annual curriculum plan in one special needs school by considering the characteristics of intellectual disabilities and the continuity from elementary to high school divisions. Based on the results of implementing the disaster mitigation education, the author analyzed its ideal methods and concrete contents for children with intellectual disabilities in special needs schools. As a result, it was effective to continuously and experientially implement disaster mitigation education based on the following three perspectives: “understanding information on disasters themselves and disaster mitigation,” “expression of danger avoidance behaviors,” and “adaptation to extraordinary situations assuming the occurrence of a disaster.”
