STU48 has had 56 original members over 2 generations (not including Draft, Kennin and transferred members) and a total of 63 members (Plus Draft, Kennin and transferred members). As of September 2021, STU48 has 40 members, although six have announced graduation.
Like in AKB48, regular auditions to recruit new members are held, and the future successful candidates, the Kenkyuusei members, take part of a in-training team of members that work as sub and under for the official members in various activities (mostly the theater performances). And then, when any of the official members graduate, a girl is promoted to fill the space.
