Episode 1

The contestants are introduced and divided into two groups: Majors and Minors. This first group division is decided purely by JYP's A&R team, not Park Jin Young. The Majors are the members currently on track to debut in the new girl group and will be treated like true JYP stars, including living in a nice dorm, riding in a van, receiving pointers from current JYP stars, and practicing from 9 am to 9 pm. The Minors are to live like trainees in a dirty dorm and are disadvantaged by a 9 pm to 9 am practice time. The members of the Major and Minor groups will change as the contestants complete missions and show their skills. Once divided, Park Jin-young issued the girls the First Mission "Are you a STAR?" which challenged them to prove that they had star potential. Contestants could freely choose what they wanted to show, but JYP wanted to "see their ability to become a star or be able to feel that [they] are meant to be a star." During this mission, Park showed favor to those who thought outside of the box and showcased themselves rather than their talents, saying "It's great to have talents, but that talent must be yours. [...] I told you to show me why you are a star; I never said to show me that you can sing or dance." No one was eliminated in this episode.
