There are four main levels a boy passes through as he develops through scouting:
Tigers, Wolves, Bears and Webelos.
Tigers
The Tiger Cub program is for first-grade (or age 7) boys 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.
Wolves
The Wolf program is for boys who have
completed first grade (or are age 8). To earn the Wolf badge, a boy must pass 12
achievements involving simple physical and mental skills.
Bears
The Bear rank is for boys 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
This program is for boys who have completed third grade (or are age 10). A boy
may begin working on the Webelos badge as 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 Handbook, 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.
