Final answer:
The three medals that may only be worn on the FFA jacket are those that represent the Highest Degree, Highest Office, and Highest Award earned at the chapter, state, or national level in the FFA.
Step-by-step explanation:
The question asks about what three medals may only be worn on the FFA jacket. The National FFA Organization, formerly known as Future Farmers of America, has specific rules regarding the decoration of the official FFA jacket. According to the official FFA manual, members are allowed to wear only three medals on their jacket. These medals represent the Highest Degree earned from the FFA, the Highest Office held at the chapter, state, or national level, and the Highest Award earned at those levels, such as state or national award medals.
It is important for FFA members to follow these guidelines as they reflect the pride, responsibility, and tradition that members carry as representatives of the organization. Wearing only these select medals ensures a uniform look among members and honors the achievements that require significant dedication and effort.
