VMI does as part of its acceptance criteria give weight to desire to pursue and accept a commission but the two departments really don't communicate back and frth.
That's what I meant about Tech, they may give weight because that is a part of their application process. I recall Tech asking if you plan to enroll in ROTC or the Corp.
However, UMD does not ask that question at all on the application, thus I suspect no weight is given. Our DS is at UMD AFROTC, thus I cannot speak for the Army det., but it would be shocking to me that admissions would talk to the Army det., and not the AF or Navy for selecting students. The Navy is small there (actually goes x town), but the Army and AF are similar in size.
Additionally, there are various types of scholarships, if the student is taking the 3 yr, 18K a yr, there is no guarantee to the school that they will ever collect the money (i.e. fails out freshman yr). Also, scholarship recipients are required to maintain specific gpas, again no guarantee that they will get the money.
For the AFROTC DET at UMD currently, 3 scholarship recipients had them revoked at the end of this yr, all do to a gpa. These students had missed it by 0.05% or less, in one case it was 0.02. If MD was banking on that money when accepting the student they now are short the bucks.
Honestly, if people think that it means the scholarship student is guaranteed money and that is why they take them, they are wrong. From a fiscal standpoint, the college is better off taking the student on FAFSA because that is GUARANTEED money! That student will not lose their grant/scholarship/loan if they fall below a 3.2 gpa, or if they get injured.
