Idol Schoolwas a 2017 reality girl group survival show on Mnet. The program aimed to form a 9-member girl group from a pool of 41 female participants, training them in singing, dancing and other "subjects" over an 11 week time period. The new group name was revealed to be Fromis 9, meaning "From Idol School", but pronounced similar to "Promise" in Korean. In August 2021, after a meeting about the group's future, Fromis 9 transferred management to Pledis Entertainment.
