Hi Catania09,
NWL means National Waiting List. Everyone is placed on the NWL=qualified candidates. Last year, I was also placed on the NWL and did not get in. However, I've heard some people get off the NWL. Based on my assumption, I think it is probably because some appointees decline their offers and those on top of the waiting list are then offered the appointment to fill the spot. I decided to ask my RC around mid April about the NWL and the RC told me that I likely wouldn't get off the NWL. But, the RC told me to reapply as a college freshman telling me that I'd be more competitive. I worked on to improve my CFA, improve my test scores,revise my essays, get solid grades in 1st semester of college, maintain a good relationship with professors. All these things really paid off. The point is that if your son happens to get rejected, he should not be discouraged, but continue to improve his profile for next year. The admissions board and the nomination committee know that your son was a previous applicant and it shows how determined he is to serve as an Army officer. Hope that helps!
