	Hundreds of candidates each day attend the global auditions held by Korean entertainment agencies to perform for the chance of becoming a trainee. Auditions include public auditions and closed auditions. Others are street-cast or scouted without auditioning, based on looks or potential talent. Those who successfully pass this audition stage are offered long-term contracts with the entertainment company. There are no age limits to becoming a trainee; thus is not uncommon for trainees, and even debuted idols, to be very young.
