Format from 2007 Divison II Nationals for 10U-13U
The 2007 Division II Nationals for these age groups did not have consistent treatment across the groups.  The summary of these 2007 Division II Nationals are as follows:
.  10-Under, 11-Under, 12-Under.  None of these D-II Nationals had a National Classic Bracket after the completion Pool Play.  Instead, every team in pool play went into a modified double elimination bracket.

.  13-Under.  Teams were split into a National Championship bracket and a National Classic bracket.    The Championship bracket was a traditional double-elimination event, while the Classic Bracket was run as a modified double elimination bracket.
