After School (애프터스쿨) is a South Korean K-Pop girl group under Pledis Entertainment. The group includes an admission and graduation concept. After School debuted in January 2009 with "AH!", from the single album "New Schoolgirl". The group currently consists of 1 member: Nana. Throughout the years, After School has gone through many lineup changes as members join and leave the group.
After School was first formed by Kahi who began planning the group together with the CEO of Pledis Entertainment. Originally, After School was a 5 member girl group that included: Kahi, Bekah, Jungah, Soyoung, and Jooyeon. The group made their unofficial appearance on December 29th, 2008, at the SBS Song Festival.
After School is known for their unique performances often incorporating different styles into their songs including drumming, tap dancing, and pole dancing. These unique styles garnered praise from Billboard who referred to After School as the "top performers in K-Pop". The group was also ranked number 5 in Billboard's list of the "Top 10 K-Pop Girl Groups of the Past Decade".
From 2015 onward, Pledis Entertainment halted After Schools's (and their sub-units) promotions as members embarked on individual music, acting, and modeling careers. In 2019, former After School member Lizzy stated that all members have gradually gone their separate ways, however, the group has not officially disbanded.
In June 2021, former After School members: Jungah, Bekah, Raina, Jooyeon, and Kahi, made an appearance on MMTG performing "Bang!", and "Diva".
