No matter what age or grade a boy joins Cub Scouting, he must earn his Bobcat badge before he can advance to the rank of Tiger, Wolf, Bear or Webelos.  The Bobcat requirements include demonstrating his understanding of Scouting's core values and being able to recite the Cub Scout Promise, Law of the Pack and Motto.  Additionally he must be able to demonstrate the Cub Scout sign, Handshake and Salute.
