country, an example being the accountancy bodies of the United Kingdom (ACCA, CAI, CIMA, CIPFA, ICAEW and ICAS), all of which have been given a Royal Charter, although their members are not necessarily considered to hold equivalent qualifications, and which operate alongside further bodies (AAPA, IFA, CPAA). Another example of a regulatory body that governs a profession is the Hong Kong Professional Teachers Union, which governs the conduct, rights, obligations, and duties of salaried teachers working in educational institutions in Hong Kong. The engineering profession is highly regulated in some countries (Canada and USA) with a strict licensing system for Professional Engineer that controls the practice but not in others (UK) where titles and qualifications are regulated Chartered Engineer but the practice is not regulated. Typically, individuals are required by law to be qualified by a local professional body before they are permitted to practice in that profession. However, in some countries, individuals may not be required by law to be qualified by such a professional body in order to practice, as is the case for accountancy in the United Kingdom (except for auditing and insolvency work which legally require qualification by a professional body). In such cases, qualification by the professional bodies is effectively still considered a prerequisite to practice as most employers and clients stipulate that the individual hold such qualifications before hiring their services. For example, in order to become a fully qualified teaching professional in Hong Kong working in a state or government-funded school, one needs to have successfully completed a Postgraduate Diploma in Education ("PGDE") or a bachelor's degree in Education ("BEd") at an approved tertiary educational institution or university. This requirement is set out by the Educational Department Bureau of Hong Kong, which is the governmental department that governs the Hong Kong education sector. Autonomy Professions tend to be autonomous, which means they have a high degree of control of their own affairs: "professionals are autonomous insofar as they can make independent judgments about their work". This usually means "the freedom to exercise their professional judgement." However, it also has other meanings. "Professional autonomy is often described as a claim of professionals that has to serve primarily their own interests...this professional autonomy can only be maintained if members of the profession subject their activities and decisions to a critical evaluation by other members of the profession." The concept of autonomy can therefore be seen
