The 11's and 12's division tournaments will use the "lighter" volleyballs during their tournaments (any USAV approved volleyball that is sanctioned for 12 and under age groups can be used). The following serving rules will be in effect in the 11 and 12 and under age group (all divisions except where noted differently below): (a) For the first regular season tournament of the sanctioned season, all 11's & 12’s divisions will establish service lines 6 feet (2 meters) and 3 feet (1 meter) inside of the normal service line. Players will be allowed the OPTION to serve from the 6 foot line on their first serve during each term of service. If the team wins the point, they must move back to the 3-foot line. If they win that point, they must serve from normal service line for the remainder of that term of service. (b) Beginning with the second tournaments of the sanctioned season and continuing to the end of the regular season, the 12's Site 1 (tournament site that has the top 8 or 12 teams assigned to it) will play using the normal service line in the USAV Rule book; all other 11's & 12's sites will play using the modified service lines described above in (a). (c) For all Regional Championship events, all 12’s divisions will play using the normal service line in the USAV Rule book. NOTE: For development purposes, all 11's sites will continue to use the step in modification in (a) for all tournaments including Regional Championship Events.
