Anime Information : Naruto Ninja Ranks #001 A-rank (Full Info)

A-rank (Aランク, Ē ranku) is one of the six classifications. It is preceded by B-rank and followed by S-rank. It is typically used when classifying techniques intended for ninja of the Kage and jōnin levels. A-rank techniques are often very useful, but need extensive training before they can be mastered. Some A-rank techniques also pose a risk to the user, resulting in their classification as kinjutsu.

There are also A-rank missions. These missions relate to what is in a village or country's personal interests and are extremely difficult or dangerous to complete, usually assigned to jōnin. A-rank missions pay between 150,000 and 1,000,000 ryō.
