The main purpose of the Accredited Registers scheme is to protect the public and raise professional standards. The Authority sets high standards for organisations holding registers and Accredited Registers require practitioners to meet high standards of personal behaviour, technical competence and where applicable, business practice. This helps protect the public.
It does not have the power to bar people from working in the same way that statutory regulation can. However, if someone is asked to leave an Accredited Register, they cannot simply join another Accredited Register. If you always choose a practitioner on an Accredited Register you can be sure they are part of a body which sets high standards and so avoid poor practice.
