Professionalization in the context of "Professional association"

Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into two – or three – major branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine.

The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (c. 3000–1200 BCE). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural philosophy of classical antiquity and later medieval scholarship, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes; while further advancements, including the introduction of the Hindu–Arabic numeral system, were made during the Golden Age of India and Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe during the Renaissance revived natural philosophy, which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in the acquisition of knowledge, and in the 19th century, many of the institutional and professional features of science began to take shape, along with the changing of "natural philosophy" to "natural science".

Contemporary philosophy is the present period in the history of Western philosophy beginning in the early 20th century with the increasing professionalization of the discipline and the rise of analytic and continental philosophy. The phrase is often confused with modern philosophy (which refers to an earlier period in Western philosophy), postmodern philosophy (which refers to some philosophers' criticisms of modern philosophy), and with a non-technical use of the phrase referring to any recent philosophic work.

In sociology, an occupational closure (or professional demarcation) is the process whereby a trade or occupation (vocation) transforms itself, or tries to transform itself, into a true profession by closing off entry to the profession to all but those people who are suitably qualified, as defined by the practitioners already practicing the occupation in any given jurisdiction. This can be achieved by licensure (occupational licensing) and professional certification, barring entry to all except those who have passed certain entrance examinations and grades of training, or by allowing entry only to those who have gained membership of a specific professional body (a professional association, such as a particular medical society). It can also be achieved by trade unionism, and most especially craft unionism as contrasted with industrial unionism, in countries where sufficient union membership (as a percentage of workers in an occupation) can be achieved despite the prevailing gradient of union busting.

What this means in practical terms, is that an architect or physician, for example, will firstly be a university graduate in their main subject, second, will have passed entrance examinations to join a recognised professional body and thirdly, will also be licensed to practise medicine or architecture, usually also obtained through sitting examinations. Therefore, such professions are open only to those who satisfy these requirements and are closed to everyone else. It is thus illegal for any other person to practice medicine or to pose as an architect.

Credentialism and degree inflation refers to processes that result in an inflation of demand for educational qualifications, and the devaluation of these educational qualifications.

Credentialism or professionalization is the growing protection of professions in modern societies by demanding formal qualifications or certifications.

The democratization of knowledge is the acquisition and spread of knowledge amongst a wider part of the population, not just elite groups such as clergy, professionals, or academia. Mass literacy, the printing press, public libraries, television, and modern information technology such as the Internet have played a key role, as they provide the masses with open access to information through a variety of means.
