Chunin exams

once every 6 years ninja from all different villages compete in a series of 3 tasks in order to become a chunin. In the anime, only Fire Country/ Konoha has been known to hold such events and is unknown whether other ninja countries hold this as well. This test usually includes three trial stages where genin are weeded out. The three proctors in the anime are Morino Ibiki, Mitsarashi Anko, and the Hokage in the final test. Morino Ibiki held the written exam part while Anko held the Forest of Death test. The Hokage and the various Jounin that accompanied the genin hold the last part of the test which are preliminary rounds and 3 months later, the final rounds where genin face each other off until one is unable to fight or is dead.
