For both of our children regarding their transcripts (2 different hs in 2 different states). The official transcript included their SAT/ACT scores and dates taken. Contact your GC to see if this is true for your school.
I agree with goalie, in this case it is always best to CYA, and send a copy snail mail too.
I would suggest that a week or so later have YOUR CHILD call to confirm the receipt. It is important that they take the lead in this situation. If you must call for him, make sure you have a valid reason. For example, one time I did call, but it was because the deadline was approaching and due to work and school issues he would be unable to connect with them during the duty day. I made it very clear in the beginning of the conversation that I was only calling due to a scheduling confliction. In other words he went straight from school to work. School started at 7 and he returned home at 9. I made the call succinct and to the point, do you have it, YES, great, thank you for your time. I didn't ask when he would go up to the board, when we would find out, what were his chances, etc.
It is important to double check that they receive all of the info, since you will be sitting on your hands believing that they went to the board, only to learn they didn't because they did not have a complete packet.
Never assume that it is complete, until you know they say it is complete.
I also impart this opinion about having your child call because next yr as an 18 yo, any ROTC problem (pay, DodMerb, etc) will be on his/her shoulders alone. They (ROTC) will not discuss any info with you since they will be a legal adult. It is best to prepare them for this while they are at home and you can guide them through the path, than when they are away at college. Trust me I speak from experience as a ROTC mom...nothing is worse when your 18/19 yo calls you freaking out late one night because they just learned about a DodMerb paperwork snafu and are freaking out since it coincides with finals.
