While the Youth Tour is a national program, students are sponsored by their local electric cooperatives and their itineraries are coordinated by the Youth Tour directors of their electric cooperative state associations.
That means that application dates and procedures are going to vary by state and even by cooperative.
What to do?
Contact your local electric cooperative for more information. They will likely have Youth Tour information posted on their website or in their newsletter. You can always check with your high school principal or guidance counselor.
Alternatively, you can contact your state association. They can direct you to your local co-op.
