What activities are prohibited for interpreters according to the CPC?

The choice highlighting participation in activities that undermine trust and integrity is accurate as it aligns with the core principles of the RID Code of Professional Conduct (CPC). The CPC emphasizes the importance of maintaining professionalism to foster trust between interpreters and clients. Engaging in activities that could potentially conflict with an interpreter's integrity or the perception of their impartiality can severely damage the professional rapport necessary for effective communication. Ensuring that interpreters conduct themselves in a manner that upholds the values of trust and integrity is critical to maintaining the professional standards expected within the interpreting community.

The other options involve behaviors that may be detrimental or unwise in a professional context but do not directly capture the fundamental prohibitions that the CPC explicitly outlines concerning trust and integrity in interpreter-client relationships. For example, engaging in personal relationships with clients can lead to conflicts of interest or ethical dilemmas, while providing services without proper credentials jeopardizes the professionalism and accountability standards. Working only in one language may limit an interpreter's scope, but it does not bear the same ethical weight in terms of trust and integrity as participating in activities that actively undermine these values.
