Parent of NROTC scholarship DD here - I would always recommend you need to try to max it out just like USNA. The scholarship is very competitive and you will want to shine in every way possible and they do look at the results. They want to know you will do well once under scholarship because to maintain it, you will have to regularly pass the fitness assessment throughout college. AND most NROTC units do not want you to just "make it over the line" - they will want every one in their unit to pass at a high level because it reflects better on their unit. The first week of school, my daughter's NROTC unit gave the PT to every one in the unit. She passed in the "good" range but they still assigned her to remedial PT (think: you get up in the morning at a time with a 4 in front of it...). She retook the test to get in the excellent category but will keep trying to get into the outstanding category.
I scored 45 pushups, which is on the border of excellent/outstanding, 78 situps, which I believe is a low excellent, and an 8:15 mile, which when converted would be a high good. My times are improving, but my recruiter told me I did well, and I submitted the scores.
Should I be concerned?
