He first wore it to the PMS interview because the PMS actually said that he would like him to.
There is the key. They wanted to see him in it and it was their recommendation. I think if the PMS requested it, than you should.
I do go with KP's logic of being well spoken and highly qualified.
Let me give you our experience. Our DS was never in AFJROTC, even though the school offered it to the students. The ALO (PMS) had 10 candidates, some were AFJROTC cadets. He was the only one out of the 10 that got every nom. available. He was given the #1 position from his ALO on his rack and stack list for recs. He was the only one to get the full ride scholarship for ROTC. Yes, not one AFJROTC received an appt or a full ride...it was the talk of the JROTC corp at the school...who is this kid, nobody in JROTC even knew of his existence. They couldn't fathom how this kid with no JROTC experience got it and they didn't.
Obviously, the uniform had nothing to do with the decision, but it was his record that had everything to do with it! WCS matters, nothing else.
It is great to wear the uniform, but I am opposed to wearing it if you think it will give you an edge in the process against other candidates. ALO's and nom committees are looking at the whole package, not what you are wearing.
CAVEAT: Show up in torn jeans and flip flops will hurt you, because their 1st impression is you are not understanding the levity of this process.
Again, I want posters/lurkers to understand that the JROTC student will not beat you out just because they are JROTC. I also don't want JROTC students to believe that this will take them up and over in the process, just by wearing their uniform. It is the
Whole
Candidate
Score. If all you have is JROTC, wearing the uniform is not going to be the make or break point.
