They usually have a special interest or skill, such as photography, clothing or gardening. Other adults help organize a group and run the meetings. Many do both. Sometimes big clubs divide and have several leaders to meet all the interests of the 4-H members. The number of leaders depends on the size of the club and how old the members are.
Some clubs have teen leaders, who usually assist adult leaders in running the club.
There are many opportunities for volunteers within the 4-H program. Contact your county extension agent for ideas. Your main help would be the county 4-H agents who are subject matter specialists in agriculture and home economics. Extension agents will invite you to special training meetings for leaders and give you the materials you need to organize a club. More than 45 projects are currently available in Tennessee.
