I have seen many go enlisted to officer and do it quickly. Now I haven't been in during the past few years so I am not sure of it as of today.
I have to disagree too. Here and over at the usnavyocs.com board, everyone is at least E-4 before they give it a shot and all the guys I know that are STA-21 at my University have 4-5 years in at least. Shoot, my father tried his guts out and for reasons that vex me to this day, he is now a retired senior chief rather than an officer. So much is out of your hands. My understanding is you can't even pass go until you earn the trust of your CO and get his endorsement. All he need do is not like you and you can forget about getting an Officer Candidacy in your first year enlisted (degree or not). I can only imagine a seaman approaching his CO with barely a year in asking him for an endorsement. What real work and character can you display in such a short time worthy of the CO's reputation?
That's just me though. Apparently you wouldn't have posted that unless you've seen different. Do you have a specific example?
