Academic ranks in Argentina

Professors are usually categorized as "ordinario" or "concursado" (tenured, selected by a jury composed of tenured professors or other reputed authorities on the subject, after a selection process involving academic background evaluation and a public dissertation), "interino" (non-tenure, but stable position, the professor is proposed by the director of the corresponding department – sometimes after different selection processes – and accepted by the Consejo Directivo of the corresponding school), or "suplente" (substitute, hired through the same process as interinos). In most cases, classes are taught by a professorial team (a "cátedra", chair), formed by one or two professors and auxiliars, which generally also functions as a research team.
