There's not much to "Hear Back Early" about.
If you were a candidate that the academy was going to give an LOA to, you probably would have heard about that by now. So, the ONLY thing to hear back about is: "YES" you received an appointment...... or "NO" you didn't receive an appointment. So, until you have a nomination in place, there's not really anything to hear from yet.
CAVEAT: There always is. Some individuals get Presidential nominations. These are for military brats and actually processed by the academy. Of all the nominations, these are some of the earliest nominations given. Depending on your application and when you applied for the presidential, you could have received this nomination back as early as July. If you have a presidential nomination, and your application is 100% completed, it is possible to hear back "Any Time" saying you received an appointment. On the other hand, admissions might hold off on giving an appointment based on a presidential nomination, to see how many presidentials they'll have and if you get any other nominations. It's also based on the individual applicant and the expected pool for that year.
This happened with my son. He had his application completed 100% in July. He also had his presidential nomination at that time. He received notification of his appointment the first of November. Before even attending any MOC nomination interviews. Had he not had a presidential nomination, he most likely wouldn't have heard anything until about January or February. Of course, if they had other individuals that they wanted to give an appointment to and they too had a presidential nomination, they could have waited on offering my son an appointment to see what nominations he got from his MOC.
So it can get quite complicated. There's so many facets to the appointment process and getting the right nomination slates filled, that it can get confusing. But the one thing is: If you don't have a presidential nomination, and you are going to be interviewing and hoping for a MOC nomination, there is absolutely no reason to expect to hear ANYTHING until after your MOC submits their nomination slate to the academy. There's no reason to contact you. Like I said previously, if you got an LOA, you probably would have gotten that by now. And unless you have a presidential nomination, there isn't a thing the academy can tell you until you "DO" or "DON'T" receive a MOC nomination. So basically, don't expect to hear anything.
Fortunately, the academy is also very flexible. They could think your application walks on water and they want to give you a late LOA to entice your MOC to give you a nomination. There's countless scenarios that the academy can do. It's their prerogative.
