North America[edit]

Under the tenure systems adopted by many universities and colleges in the United States and Canada, some faculty positions have tenure and some do not. Typical systems (such as the widely adopted "1940 Statement of Principles on Academic Freedom and Tenure" of the American Association of University Professors^[3]) allow only a limited period to establish a record of published research, ability to attract grant funding, academic visibility, teaching excellence, and administrative or community service. They limit the number of years that any employee can remain employed as a non-tenured instructor or professor, compelling the institution to grant tenure to or terminate an individual, with significant advance notice, at the end of a specified time period. Some institutions require promotion to Associate Professor as a condition of tenure. An institution may also offer other academic positions that are not time-limited, with titles such as Lecturer, Adjunct Professor, or Research Professor, but these positions do not carry the possibility of tenure and are said to be not "tenure track." Typically, they have higher teaching loads, lower compensation, little influence within the institution, few if any benefits, and little protection of academic freedom.
