Inspecting and enforcing regulations is a profession, which is distinct from that of being a technical specialist (of specific environmental or health issues, for instance). While it requires technical knowledge and skills, they are but a part of what is needed. Defining the profession of inspector as one distinct from that of technical specialist is an important element, and with it goes the need to delineate what competences are needed for inspectors: understanding and managing risks, communicating and advising, promoting and supporting compliance, investigating etc. Only professional inspectors, with a full understanding of their mission and of the tools that can be used to fulfil it (and of their limitations) can adequately exercise discretion. Such a framework for the inspection profession should be officially stated, and form the basis for recruitment practices, job descriptions, training, professional assessments and performance evaluation for staff.
