It partly depends on which ceremony - the regular/state ceremony or the Grand Ceremony. We did not attend the big NUMATS one at Northwestern even though DS was awarded a scholarship for first place because it was so far and because we were already attending the CTY Grand Ceremony. I am not sure if the difference with NUMATS is the same as the difference between the regular honors CTY ceremony and the CTY Grand Ceremony. If yes, then it may be worth attending. The Grand Ceremony took about an hour with guest speakers, followed by group pictures, a luncheon, and a campus tour of Hopkins. If NUMATS has the same distinction and there is an interest in Northwestern, then it may be worth it. I don't remembered what NUMATS offered.
