A Merit Badge Counselor is a volunteer who helps Boy Scouts earn merit badges by providing guidance and expertise in specific subjects. They work with scouts to teach skills, review their work, and ensure they meet the requirements for each badge. Counselors can specialize in various areas, such as first aid, cooking, or environmental science. To become a merit badge counselor, individuals must complete an application process, which includes background checks and training. They play a crucial role in the scouting experience, fostering personal growth and encouraging scouts to explore new interests and develop valuable skills.
