A professional affiliation is a group or organisation to which a person belongs because of his or her involvement in a specific profession. A nurse, for example, could become a member of the American Nurses Association. Paid memberships to active participation in group activities or leadership roles are all examples of affiliations.
People frequently add a “Professional Affiliations” section on their resumes. Participation in professional associations may persuade a hiring manager that a person is truly passionate about their work. It also implies a willingness to get involved in ways that aren’t strictly related to employment. A person can also be a member of the associated organization’s board of directors.
