All leaders have to take part in training relevant to their role and on the job validation until they complete their training. The Wood Badge is then awarded to adults in Scouting who complete their training. It is awarded to Scouts around the world and all those who achieve their badge automatically become a member of the 1st Gilwell Park Scout Group, the largest in the world.
There is also regular mandatory training that help keep leaders skills fresh. The links below will help you find the training material on the Scout Association Web Site
