We do not know of research that is specific to the role of peers in IPS. Many IPS supervisors do hire peers, though their roles vary from program to program. In some programs, the peers provide supports in addition to the work done by the employment specialist. They might encourage someone to work in spite of different barriers, or they might provide additional job supports. In other areas, IPS supervisors hire employment specialists who happen to have a lived experience of mental illness and are willing to share how they have overcome difficulties and benefited from work with the people they serve. These supervisors look for people who are qualified to do the job of an employment specialist, and they view lived experience as an added qualification.
