The objective of the current study is to develop a program that will instill a positive perception of disabilities in preservice social welfare workers. Among students of social welfare in D University in city K in Province K in Korea, five with volunteer service experiences in facilities for disabled people were selected for the current study to conduct phenomenological research. Two researchers met face-to-face with the five research participants to interview them about the experiences of volunteer service activity in facilities for disabled people. Agreements were obtained from the participants to record the interviews which were in turn transcribed. The transcriptions were analyzed, which involves categorization of statements that were interpreted as reflecting the participants’ changes to their perception of disabled people. The current study concludes the following: First, volunteer service activities in facilities for disabled people allowed preservice social welfare workers to reduce their prejudice and misperceptions about disabled people. Specifically, they realized that disabled people do not always require help, and are not very different from non-disabled people. Second, the volunteer services helped the preservice social welfare workers to form close relationships with disabled people. The disabled people were initially perceived as unfamiliar and even frightening individuals, but through the service, the participants came to perceive them as friends and family, forming more intimate relationships. Third, the service experience made the preservice social welfare workers understand that practical education in schools and jobs is required to change perceptions about disabilities.
