Don't assume a deferral in EA equates to a rejection in regular decision. This varies greatly by school. My DS was deferred EA to his top choice school last year, then was admitted regular decision. When he was deferred, he had already been awarded his NROTC scholarship and it was placed at this school. If your DS has been awarded a scholarship and assigned to a school where he was deferred, my suggestion would be for him to write a short letter of interest via email, stating his desire to attend that school and that he has a NROTC awarded to him at that school. I would also suggest to him that he reach out to the NROTC unit staff at that school to update them on his status. For some schools, but not all, the unit staff have some influence on admissions decisions. These are the steps my DS took last year and it worked out for him.NROTC assigned the scholarship to his top Plan B school, and he was deferred in the Early Action Round (as expected), so we wait, and the NROTC option hangs on for dear life. But, DS is aware that deferral most likely equates to rejection in the RD Round. Fortunately, he was awarded a Type I AFROTC Scholarship, so his options are now a little more flexible. He's been accepted to several schools where he can use his AF Scholarship, including one where he received a $25K per year merit scholarship, and that school has agreed to convert the university award to cover room and board (15K per year). So at that school, it's a full scholarship opportunity for him.
When my DD was rejected EA, but already had NROTC scholarship, she changed her request for NROTC school to one she knew she would be accepted to, as advice we were given suggested to place it at the 'sure' school, just so she'd have a place in that class until we heard from all the schools. Once she did hear, she ended up changing it to a third school that was a better fit (not the 'sure' school, which would've been her standby). We were told that at some of the popular schools their units fill up fast, and getting accepted and having space in the unit could be vastly different. This worked for my DD. Good luck, and congrats on his scholarship in the first place!Thanks cb7893, his letter will include that again, but the school already knew about his NROTC award before deferral so it's probably a non-factor. He was right in the 50th percentile for stats. This is a very competitive year for colleges and academies!
