Public service interpreting (PSI) is an emerging professional grouping within the interpreting profession. The challenges faced by public service interpreters are often more akin to those faced by AHPs (Allied Health Professionals) and clinicians than they are to those in other interpreting fields. The nature of these challenges is a training issue in itself. Furthermore, the need for public service providers (PSP) to understand the professional purposes and needs of their interpreters and to incorporate them into the multidisciplinary team on the basis of an understanding mind is often overlooked. The result can be like a dance with three participants, of whom only one knows the steps. This chapter attempts to outline some of these issues, advance discussion of and encourage research into such matters as client education and improved interdisciplinary understanding and collaboration.
