Every NRD seems to have their own policies. When I first contacted my NRD, they said they would put me into contact with an OR early the following week...Never happened so I called back, but was able to find an extension for an OR online, so that put me into direct contact with him. He told me kind of what they're telling you, study for the ASTB, then contact so-and-so when you're ready to take it so it can be scheduled. The first time I met my recruiter was the day I took the test, and he actually spent a good deal of time with me. It's getting to the point from a competitiveness standpoint (at least with most designators, I applied SNA) where I've been hearing they won't give you much of their time if you don't score well on the test. So at this point, the best advice I can give you is to study your butt off and nail the test. Good scores will get you noticed. IF you by chance don't do well on the test, make it known to your recruiter that you still want this, and that you're willing to do what it takes to make YOUR dream come true. Always keep that in mind when dealing with an OR, this is YOUR dream, not his/hers. Their job is not to make you become an officer, it's to facilitate you making yourself an officer, they won't/shouldn't hold your hand. Also, the test is not the only important part of your package, you can usually make up for a lower than you wanted score with other things, but nowadays, you probably can't make up for "low" scores (which is also a completley subjective term). Your OR should be able to help you determine how competitive your scores are when the time comes.
Aside from that, the process can move slowly sometimes, so just do your best to stay motivated, and help your OR by being proactive. There's lots of good gouge on the ASTB in the appropriate threads on this site, which should help you for now. Best of luck!
