My DS is a senior in high school and the recipient of a 4 year NROTC scholarship as a Tier 1 student. I'm hoping someone with real knowledge of how this stuff works might be able to shed some light on the below. 1. I know that one can request to be assigned to another NROTC unit. Is that very difficult? He received his first choice (Virginia), but is now uncertain as to whether he'd rather apply it to his second choice (Duke) or third choice (Stanford). 2.Is it possible to request that one be permitted to be a Tier 3 student? If so, is anyone familiar with the process, its difficulty and the odds? 3.In relation to both above questions: does it matter whether these requests are made before or after acceptance of the scholarship? I presume they would be made afterward. Thank you in advance.
