Teachers at institutions of higher learning in the Czech Republic have titles corresponding to their hierarchical classification – the highest title is that of a professor („profesor”), the medium level title being that of an associate professor („docent”) and the lowest level title being that of an assistant professor („odborný asistent”). In the course of routine interaction, it is sufficient to use the title „doctor“ or „professor“. In the Czech Republic it is not customary to use first names when addressing faculty teachers or its staff – in the case of a faculty's staff, it is customary to use the titles „Mr / Mrs / Miss“.
