The bell test is a form of examination that is given to the KonohagakureAcademy Students who have managed to graduate from the Academy. The jōnin who has been assigned to test out the three-man cell will use this test to determine whether the three students are worthy of being officially promoted into genin, sent back to the Academy for further training, or even dropped from the programme altogether for overly poor performance.[1] It is unknown if all Konoha teams are tested by such a test, as only Team Hiruzen and Team Kakashi were seen undergoing it.
