Professional development, also known as professional education, is learning that leads to or emphasizes education in a specific professional career field or builds practical job applicable skills emphasizing praxis in addition to the transferable skills and theoretical academic knowledge found in traditional liberal arts and pure sciences education. It is used to earn or maintain professional credentials such as professional certifications or academic degrees through formal coursework at institutions known as professional schools, or attending conferences and informal learning opportunities to strengthen or gain new skills.

Professional education has been described as intensive and collaborative, ideally incorporating an evaluative stage. There is a variety of approaches to professional development or professional education, including consultation, coaching, communities of practice, lesson study, case study, capstone project, mentoring, reflective supervision and technical assistance.

A profession is a field of work that has been successfully professionalized. It can be defined as a disciplined group of individuals, professionals, who adhere to ethical standards and who hold themselves out as, and are accepted by the public as possessing special knowledge and skills in a widely recognised body of learning derived from research, education and training at a high level, and who are prepared to apply this knowledge and exercise these skills in the interest of others.

Professional occupations are founded upon specialized educational training, the purpose of which is to supply disinterested objective counsel and service to others, for direct and definite compensation, wholly apart from expectation of other business gain. Medieval and early modern tradition recognized only three professions: divinity, medicine, and law, which were called the learned professions. In some legal definitions, a profession is not a trade nor an industry.

A psychologist is a professional who practices psychology and studies mental states, perceptual, cognitive, emotional, and social processes and behavior. Their work often involves the experimentation, observation, and interpretation of how individuals relate to each other and to their environments.

Psychologists usually acquire a bachelor's degree in psychology, followed by a master's degree or doctorate in psychology. Unlike psychiatrists and psychiatric nurse-practitioners, psychologists usually cannot prescribe medication, but depending on the jurisdiction, some psychologists with additional training can be licensed to prescribe medications; qualification requirements may be different from a bachelor's degree and master's degree.

Professional ethics encompass the personal and corporate standards of behavior expected of professionals.

The word professionalism originally applied to vows of a religious order. By no later than the year 1675, the term had seen secular application and was applied to the three learned professions: divinity, law, and medicine. The term professionalism was also used for the military profession around this same time.

As a selling technique, a sales presentation or sales pitch is a line of talk that attempts to persuade someone or something, with a planned sales presentation strategy of a product or service designed to initiate and close a sale of the product or service.

A sales pitch is essentially designed to be either an introduction of a product or service to an audience who knows nothing about it, or a descriptive expansion of a product or service that an audience has already expressed interest in. Sales professionals prepare and give a sales pitch, which can be either formal or informal, and might be delivered in any number of ways. A sales pitch may be invited by an organization looking to obtain supplies or services, for example in a commissioning context.

Social exchange theory is a sociological and psychological theory which studies how people interact by weighing the potential costs and benefits of their relationships. This occurs when each party has goods that the other parties value. Social exchange theory can be applied to a wide range of relationships, including romantic partnerships, friendships, family dynamics, professional relationships and other social exchanges. An example can be as simple as exchanging words with a customer at the cash register. In each context individuals are thought to evaluate the rewards and costs that are associated with that particular relationship. This can influence decisions regarding maintaining, deepening or ending the interaction or relationship. The Social exchange theory suggests that people will typically end something if the costs outweigh the rewards, especially if their efforts are not returned.

The most comprehensive social exchange theories are those of the American social psychologists John W. Thibaut (1917–1986) and Harold H. Kelley (1921–2003), the American sociologists George C. Homans (1910–1989), Peter M. Blau (1918–2002), Richard Marc Emerson (1925 –1982), and Claude Lévi-Strauss (1908–2009). Homans defined social exchange as the exchange of activity, tangible or intangible, and more or less rewarding or costing between at least two persons. After Homans founded the theory, other theorists continued to write about it, particularly Peter M. Blau and Richard M. Emerson, who in addition to Homans are generally thought of as the major developers of the exchange perspective within sociology. Homans' work emphasized the individual behavior of actors in interaction with one another. Although there are various modes of exchange, Homans centered his studies on dyadic exchange. John Thibaut and Harold Kelley are recognized for focusing their studies within the theory on the psychological concepts, the dyad and small group. Lévi-Strauss is recognized for contributing to the emergence of this theoretical perspective from his work on anthropology focused on systems of generalized exchange, such as kinship systems and gift exchange.

A vocational school (alternatively known as a trade school, or technical school), is a type of educational institution, which, depending on the country, may refer to either secondary or post-secondary education designed to provide vocational education or technical skills required to complete the tasks of a particular and specific job. In the case of secondary education, these schools differ from academic high schools which usually prepare students who aim to pursue tertiary education, rather than enter directly into the workforce. With regard to post-secondary education, vocational schools are traditionally distinguished from four-year colleges by their focus on job-specific training to students who are typically bound for one of the skilled trades, rather than providing academic training for students pursuing careers in a professional discipline. While many schools have largely adhered to this convention, the purely vocational focus of other trade schools began to shift in the 1990s "toward a broader preparation that develops the academic" as well as the technical skills of their students.

A trade show, also known as trade fair, trade exhibition, or trade exposition, is an exhibition organized so that companies in a specific industry can showcase and demonstrate their latest products and services, meet with industry partners and customers, study activities of competitors, and examine recent market trends and opportunities.

In contrast to consumer shows, only some trade shows are open to the public, while others can only be attended by company representatives (members of the trade, e.g. professionals) and members of the press, therefore trade shows are classified as either "public" or "trade only". A few shows are hybrids of the two; one example is the Frankfurt Book Fair, which is trade only for its first three days and open to the general public on its final two days. They are held on a continuing basis in virtually all markets and normally attract companies from around the globe. For example, in the U.S., there are currently over 10,000 trade shows held every year, and several online directories have been established to help organizers, attendees, and marketers identify appropriate events.

A vocation (from Latin vocatio 'a call, summons') is an occupation to which a person is especially drawn or for which they are suited, trained or qualified. Though now often used in non-religious contexts, the meanings of the term originated in Christianity.

A calling, in the religious sense of the word, is a religious vocation (which comes from the Latin for "call") that may be professional or voluntary and, idiosyncratic to different religions, may come from another person, from a divine messenger, or from within oneself.
