Difference between 委嘱状・任命状・任命証


If the talk is about appointing the representative of Internal Management
System (IMS) (in some company), which one will be suitable in this situation?
:

Letter of appointment (to a position): 委嘱状 【いしょくじょう】・任命状【にんめいじょう】・任命証
【にんめいしょう】・辞令【じれい】




A 辞令 is an appointment notice issued typically by a president to his/her
employee. It typically looks [like

it's usually very short, blunt, and not polite at all :)

委嘱 is a respectful word used when someone asks someone to do a job that
requies sophisticated expertise. I feel external consultants/advisors are
often invited using the term 委嘱. 任命 is similar in meaning but sounds more
"authoritative" (both in positive and negative senses). Which to use 委嘱 or 任命
would depend on the relation between the two.

As for the difference between ～証 and ～状, the former literally means
"certificate for ～" and the latter literally means "notice/letter for ～". I
think I see ～状 far more often, but there should be no big difference in this
case.
