Sessional lecturer or sessional instructor are contract faculty who hold full- or part-time teaching positions and may perform administrative duties but have no research responsibilities. Sessionals hold short-term contracts, typically running one or two academic terms; in many post-secondary institutions sessional contracts may be renewed repeatedly but by definition, they offer no legal expectation of ongoing work. Unlike members of other academic ranks, sessional lecturers are ineligible for tenure. It is an academic rank for a type of job common in Canadian and Australian universities and colleges.
