I'm sorry for the mixup, I answered this question in a personal
response email to Delaware and forgot to post to the board. The
rules for eligibility for ATC are that all players on a team must be
affiliated with the same school, and they may be undergraduate or
graduate students. It is not exclusively meant for novice teams or
undergraduates, but the difficulty level is aimed to be accessible
to less experienced players. Thanks for bringing it up.
