You are correct, it is a special term for the Boy Scouts. A "badge of merit" or "merit badge" is an ornament similar to a medal that is given to someone in recognition of an achievement or successfully overcoming a challenge. "Merit" is a quality that describes someone or something as being particularly good, worthy or outstanding in some capacity. A "badge" is a wearable indicator that someone is a member of a group or has earned some award. Ex: I couldn't earn the merit badge for fishing because I didn't catch any fish. Ex: My father was in the boy scouts when he was younger, and he earned a bunch of merit badges.
