How does one become a Jounin? It is said in the wiki that:


  ...there was mention of a Jōnin Exam in the anime's Kurama Clan Arc.


Does anyone here know what are the stages/steps/missions in order to be a Jounin?
I think recommendation to become Jōnin ninja are send by villagers and the hokage has the final decision of a making a one.

I'm not sure about this but I think that the candidate has to create a new jutsu in order to become a Jōnin (like Kakashi with Chidori, Minato with Rasengan).

We don't get any other details other than this. Same for the exam. I think that the created jutsu will be examined.

My answer is based on the anime.
