Join AFJROTC Air Force JROTC is for students above the 8th grade. If your school does not have a JROTC program, the only way you can join JROTC is if another school nearby has a unit and will allow you to attend the class. That would be up to the principal of the school and the JROTC instructor at the school.
Air Force Junior ROTC is located in more than 869 high schools across the nation and overseas. Visit our AFJROTC Units page to find a unit near you.
If your school doesn't have an AFJROTC unit and you are looking for aerospace training, you might want to talk with a local Civil Air Patrol unit.
