P. Eng.

Regulation and licensure in engineering is established by various jurisdictions of the world to encourage public welfare, safety, well-being and other interests of the general public, and to define the licensure process through which an engineer becomes authorized to practice engineering and/or provide engineering professional services to the public.

As with many other professions, the professional status and the actual practice of professional engineering is legally defined and protected by law in some jurisdictions. Additionally, some jurisdictions permit only licensed engineers (sometimes called registered engineers) to "practice engineering," which requires careful definition in order to resolve potential overlap or ambiguity with respect to certain other professions which may or may not be themselves regulated (e.g. "scientists," or "architects"). Relatedly, jurisdictions that license according to particular engineering discipline need to define those boundaries carefully as well so that practitioners understand what they are permitted to do.

In many cases, only a licensed/registered engineer has the authority to take legal responsibility for engineering work or projects (typically via a seal or stamp on the relevant design documentation). Regulations may require that only a licensed or registered engineer can sign, seal, or stamp technical documentation such as reports, plans, engineering drawings, and calculations for study estimate or valuation, or carry out design, analysis, repair, servicing, maintenance, or supervision of engineering work, process or project. In cases where public safety, property or welfare is concerned, it may be required that an engineer be licensed or registered – though some jurisdictions have an "industrial exemption" that permits engineers to work internally for an organization without licensure so long as they are not making final decisions to release product to the public or offering engineering services directly to the public (e.g. consultant).

Expert witness or opinion in courts or before government committees or commissions can be provided by experts in the respective field, which sometimes is given by a registered or licensed engineer in some jurisdictions.

Becoming an engineer is a process that varies widely around the world. In some regions, use of the term ' engineer ' is regulated, in others it is not. Where engineering is a regulated profession, there are specific procedures and requirements for obtaining a registration, charter or license to practice engineering. These are obtained from the government or a charter-granting authority acting on its behalf, and engineers are subject to regulation by these bodies. In addition to licensure, there are voluntary certification programs for various disciplines which involve examinations accredited by the Council of Engineering and Scientific Specialty Boards.
