Being a young volunteer provides an opportunity for volunteers to build stronger awareness of social issues, such as the fulfilment of equal rights for persons with disabilities. For young volunteers, participation in volunteerism can form strong characters. This research attempts to describe the forms of strength of character in young volunteers for persons with disabilities and their development. Data collection methods used were Online Survey (Study 1) and Nominal Group Technique and Focus Group Discussion (Study 2). Both studies involved young volunteers in communities and organizations with disabilities in Malang Regency and Kota aged between 18-30 years (Study 1 with N= 59 people and Study 2 with N= 6 people). From the research, it is found that the character strength becomes the modality of participation as a volunteer and develops in the process of involvement of young volunteers for persons with disabilities.
