Any NJROTC/MCJROTC honor unit (for NJROTC, a unit that has earned the Distinguished Unit Award) can submit six nominations to USNA. Any other NJROTC/MCJROTC unit can submit three nominations to USNA. These are legitimate nominations, but the quota for appointments to be made by these nominations is something like twenty per year for USNA. Definitely not a nomination source to depend on. I got an NJROTC nomination, but was appointed off of my congressman's slate in the end anyway.
