The UNAM counts with a kind of "ranks" which exists separately for lecturers (profesor), reseachers (investigador) and technicians (técnico académico).
|
Investigador/ Profesor/ Técnico | Asociado A |
| Asociado B | |
| Asociado C | |
|
Investigador/ Profesor/ Técnico | Titular A |
| Titular B | |
| Titular C |
The lowest rank is Asociado A, the highest Titular C. Payment and the right to participate in commissions, councils etc. depend greatly on the level. Requirements to obtain a position as lecturer or researcher are (as I believe) somehow equivalent but lower for tecnicians. Requirements to be able to rise within the hierarchy vary from institute to institute.
