Sisters' Class is a South Korean reality/variety show broadcast by MBS TV every Saturday evening. It originally premiered in February 2018 and has since aired for over five seasons. The program, though features flexible settings, largely features a high school classroom setting with the fixed cast, mostly consisting of industry veterans, acting as same-aged student. Guests arrive posing as visiting students from another school and are interviewed by the cast in a talk show segment; the program's second half usually features a variety segment, with the cast and guests taking of activities such as games, talent show, or quizzes.
Sisters' Class' main cast consists of the titular Three Sisters, Hwang Yugeum, Kim Meita, and Park Juhwang, alongside other television personalities such as Yong Hwa, Kim Yuwon, Lee Bohyung, Jang Taeryeong, Choi Dahyun, Lady Ruby, Xavier Luna, and MIIX. The show has received accolades over the 2020s and is currently the most successful variety program on MBS, receiving weekly ratings of 6-8%. It has been nicknamed "the second coming of Downtown Plaza", referring to MBS' legendary late night variety show from the 1990s. Guests on the show have included singers, actors, Olympic and national athletes, as well as other popular television personalities. The show has also launched project groups such as the co-ed group Randomize, five-member boy group Sugartime, and pop rock band Midlife Crisps, the second of which was formed through the survival show parody segment You Think You Can Debut?
The current format explores an early 2000s South Korea-esque high school setting where the cast members act like students in a classroom while guests come as newly transferred students. Most of the segments for this format portray activities that every student would do with their classmates. Subsequently, the program sometimes diversifies at the end with a segment outside of the school concept. This format has received praise from the viewers and led to a significant increase in ratings and popularity of the program.
A noteworthy aspect of the show is the usage of informal language (banmal; 반말) manner of speech used by everyone regardless of age or seniority, thus marking the absence of the Korean language's strict seniority rules with spoken language and the sunbae–hoobae hierarchy in the Korean entertainment industry. The casual setting encourages the guests and cast to interact with each other as people of the same age often do, leading them to be comfortable enough to tease one another.
