Hello Pro Kenshuusei (ハロプロ研修生; Hello Pro Trainee) (formerly Hello Pro Egg (ハロプロエッグ)) is a collection of young girls selected through auditions, or added specially by Tsunku, that are receiving dance and vocal lessons in the hopes that they will one day be able to debut as full idols within Hello! Project. Not yet being full members within Hello! Project, the girls mainly perform at Hello! Project concerts as backing dancers for the major acts. The Kenshuusei also hold their own concerts and have their own songs.
