He received his on the 2nd board. I can say that he wasn't so high on the 2nd board that it got bumped to a 4 year after the 3rd board which is what happened to a friend of his.
There's always the campus-based scholarships, so don't give up hope if he doesn't get awarded on the 3rd board. Someone posted that their child got a 3.5 year campus-based scholarship, which made me feel like earning the 3 year national wasn't as great a benefit as I thought. However, definitely nice going into the start of college knowing where you stand.
