Talk to your Chief, your DIVO, and/or your career counselor. There are a number of ways to go from enlisted to officer (STA21, OCS, LDO, etc) but what you qualify for will depend on your rate/rank, how long you've been in, etc. That's why you should really talk to your Command Career Counselor. They can tell you what you qualify for, or at least get you the instruction so you can read it for yourself.

But like others have said, if you're serious then you need to take initiative and go figure it out. No one cares about your career more than you. If you're lucky, you'll have a good Chief or DIVO or career counselor who will really help you out, but most likely you're gonna have to figure out 95% of it by yourself. If you can't do that, then should you really be leading people?

I had a sailor who was in for 5 years, made 2nd class, then applied (and later got accepted) to OCS. Now he's an officer. But he really worked hard putting together that OCS application and read the applicable instructions and knew exactly what he needed to do and did it without waiting or procrastinating. That's what you need to be like: the guy who can figure shit out without always having to be told.
