For example, adjuncts are non-tenure-track faculty in the U.S. and in Canada. In Canada in particular, adjunct professors are often nominated in recognition of active involvement with the appointing institution, while they are employed by government, industry, a profession or another institution. Unlike in the US, if the appointment is strictly to teach one or more courses, the Course Lecturer appointment is used instead.
In contrast, a similar designation, Professor adjunto, does imply stable full-time employment in countries such as Argentina and Brazil.
In parts of Spain, Profesor Adjunto is a non-tenured position. There exist similar Adjunktus in Hungary. In Thailand, Adjunct (Assistant/Associate) Professors are considered "non-regular officers".
