How do I find out if my high school will have a Junior ROTC program and what do I do if I absolutely want to join a Junior ROTC program?
Talk to your school councilor and see if she knows if your school is going to participate in a ROTC program. And if not does she know where you could participate in one or look into it for you.
Most High school's have a website you can check for classes! Try googling your school and zip code and it should come up.
