Genin are put in four-man cells or squad, consisting of three genin and a Jōnin-sensei, in order to learn teamwork and experience true ninja life under the supervision and protection of an elite shinobi. The make-up of these teams is based on the individual skills of the genin, so that there will be a balance between the teams. Teams are occasionally organized into groups with two boys and one girl, and are also balanced depending on Academy scores and general skill levels.
Due to the fact that genin are the lowest level ninja, they normally provide limited use during dangerous missions (B-rank or higher), and are usually only capable of successfully completing E-rank or D-rank techniques. However, it should be noted that genin is simply a rank, and is not always an accurate representation of a ninja's skill level. Some Genin choose to remain at their rank due to past mistakes that prevent them from moving forward, while others simply do not possess the level of maturity or tactical prowess required for promotion.
Academy Students are promoted to Genin after participating in the Genin Exam and passing. The Genin Exam is a relatively simply process and only requires for the students to take a written exam, following by a set of tests to see if they are capable of producing successful jutsu. Though genin are relatively low-levelled ninja, they can progress to become a Chūnin by successfully completing the chūnin exams, a set of difficult tasks made to test the skills of genin to see whether or not they should be Chūnin.
