Continuing education, also known as lifelong education or lifelong learning is an all-encompassing term within a broad list of post-secondary learning activities and programs. The term is used mainly in the United States and Canada.

Recognized forms of post-secondary learning activities within the domain include: degree credit courses by non-traditional students, non-degree career training, college remediation, workforce training, and formal personal enrichment courses (both on-campus and online).

General continuing education is similar to adult education, at least in being intended for adult learners, especially those beyond traditional undergraduate college or university age.

Frequently, in the United States and Canada continuing education courses are delivered through a division or school of continuing education of a college or university known sometimes as the university extension or extension school. The Organisation for Economic Co-operation and Development argued, however, that continuing education should be "'fully integrated into institutional life rather than being often regarded as a separate and distinctive operation employing different staff' if it is to feed into mainstream programmes and be given the due recognition deserved by this type of provision".

Georgetown University, Michigan State University, and the University of Denver have benefited from non-credit programs as it relates to strengthening partnerships with corporations and government agencies, helping to inform and shape the curriculum for degree programs, and generating revenue to support the academic enterprise.
