Recognition is important to Scouts. The Cub Scout advancement plan provides fun for the children, gives them a sense of personal achievement as they earn badges, and strengthens family understanding as adult family members work with boys and girls on advancement projects.
Bobcat - The Bobcat rank is the first rank for anyone who joins Cub Scouting at any age or grade level.
Tiger Cub - The Tiger Cub program is for first grade (or age 7) children and their adult partners. There are five Tiger Cub achievement areas. The Tiger Cub, working with his adult partner, completes 15 requirements within these areas to earn the Tiger Cub Badge. These requirements consist of an exciting series of indoor and outdoor activities just right for a boy in the first grade.
Wolf - The Wolf program is for children who have completed first grade (or are age 8). To earn the Wolf badge, a boy must pass twelve achievements involving simple physical and mental skills
Bear - The Bear rank is for children who have completed second grade (or are age 9). There are 24 Bear achievements in four categories. The Cub Scout must complete 12 of these to earn the Bear badge. These requirements are somewhat more difficult and challenging than those for Wolf rank.
Webelos I & II - This program is for children who have completed third grade (or are age 10). A boy may begin working on the Webelos badgeas soon as he joins a Webelos den. This is the first step in his transition from the Webelos den to the Boy Scout troop. As he completes the requirements found in the Webelos Scout Book, he will work on activity badges, attend meetings led by adults, and become familiar with the Boy Scout requirements all leading to the Arrow of Light Award.
You can earn other awards too. The religious award is to help scouts grow stronger in their faith.
The US Scouting Service Project has a wealth of information about all things Cubs and Boy Scouts including blogs and forums.
