A "Rookie Grand Slam" is when an artist is able to win the awards that honor the best performing new artists of the year at five major award shows of South Korea. These award shows are MelOn Music Awards (MMA), Mnet Asian Music Awards (MAMA), Golden Disk Awards (GDA), Gaon Chart Music Awards (GCMA), and Seoul Music Awards (SMA). (Note that Korean Music Awards (KMA) is one of, if not the most highly regarded award shows of South Korea, but no idol group has won Rookie of the Year at KMA as of December 2021.)
