The Webelos badge is the fourth rank in Cub Scouting. A Cub can start on it as soon as he joins a Webelos den, and providing he has completed third grade (or is 10 years old.) He can earn the Webelos badge after he has been in the den 3 months.
One of the differences between Webelos and younger Cub Scouts is that the Webelos Den Leader signs off the completed activities of a Webelos Scout.
As with all other Cub Scouting ranks, new members of the Webelos Den or patrol must complete the Bobcat requirements before beginning work in the Webelos program.
The Arrow of Light Award is the highest rank in Cub Scouting. A Webelos Scout should set his sights on it early. It's tougher to earn than the Webelos badge, but he can do it! The Cub Scout will have to earn the Webelos badge and at least eight activity badges, including: Citizen, Readyman, and Fitness. The total must include one from each of the five activity groups.
By the time he has earned the Arrow of Light Award, he will have learned many things about a lot of subjects - and a lot about Boy Scouting. He will be ready to join a Boy Scout troop!
Before he get's started on the Arrow of Light Award, he should read through the requirements with a parent, guardian, or den leader. Each time a requirement is satisfied, he should have his Webelos Den Leader sign it off in his Webelos Scout Book.
