Boy Scouts: Cub Scouting is for boys in the first through fifth grades, or 7 to 10 years of age. Boys who are older than 10, or who have completed the fifth grade, can no longer join Cub Scouting, but they may be eligible to join the Boy Scouting or Venturing program depending on their age and grade level.
Boy Scouts: Youth can join a Scout troop who have earned the Arrow of Light rank and are at least 10 years old, or have completed the fifth grade and are at least 10, or who are 11, but not yet 18 years old.
