E-rank

E-Rank is one of the six classifications. It is followed by D-Rank. It is used exclusively when classifying jutsu intended for Academy Students. A number of E-Rank jutsu must be learned before ninja can graduate, and are only difficult in the sense that students may not have learned how to properly control their chakra. With time, E-Rank jutsu like the Body Replacement Technique become second nature for seasoned ninja.

Trivia
E-rank is the only rank not used for ranking Missions or Missing-nin.
