A2O

A2O is a collaborative global artist development platform where Rookies receive training in one of four groups, organized by age. A2O is also a group name. As the Rookies mature, LTB will advance to HTB, and LTG will transition to HTG. The following are four age-based classifications for A2O Rookies:

LTG: Low Teen Girls (15 and Under)
LTB: Low Teen Boys (15 and Under)
HTG: High Teen Girls (16 and Up)
HTB: High Teen Boys (16 and Up)

A2O system is compromised of four key stages: Trainee, Rookies, Unit and Artist/Team. Trainees are those who undergo rigorous training as part of A2O but remain unrevealed to the public. The Rookies stage marks a significant milestone where trainees are introduced to the public through the A2O Channel and A2O’s diverse content. A2O Units are dynamic subgroups formed by bringing together Rookies based on their unique talents, charm, and artistic synergy. The final stage is where individuals officially debut as A2O artists by releasing their original music, music videos, and performances solo or as a team.

Throughout their training, the Rookies will showcase captivating performances on the A2O Channel, either as solo acts or as units. Please join us in supporting these Rookies as they develop and debut as artists!
