To join, a certifying entity must provide a scope of practice document and refer to scope of practice in the profession's code of conduct and in its professional standards. If it has no separate scope document, the references in the code and the professional standards stand as the evidence. The scope covers any role in which a practitioner uses their professional skills (paid or unpaid, clinical or not, including management, education, research and policy), the entity should say how it helps practitioners work to their full scope safely, and it may define advanced and extended scopes. Professional standards underpin scope and should be public.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
