Merit Badges 成就徽章
You can learn about sports, crafts, science, trades, business, and future careers as you earn merit badges. There are more than 130 merit badges. Any Boy Scout may earn a merit badge at any time. You don't need to have had rank advancement to be eligible.
Pick a Subject. Talk to your unit leader (Scoutmaster) about your interest in earning a merit badge. Read the requirements of the merit badges you think might interest you. Choose one to earn. Your unit leader will give you a signed merit badge application (the "blue card") and the name and contact information of a merit badge counselor. These individuals have special knowledge in their merit badge subjects and are interested in helping you.
Use the Scout Buddy System. You must have another person with you at each meeting with the merit badge counselor. This person can be another Scout, your parents or guardian, a brother or sister or other relative, or a friend.
