YELLOW DIVISION = RATED 3-4

• The YELLOW division is competitive.
• Players are required to be well-versed in CGVA and general volleyball rules.
• Players are expected to play in 5-1, 6-2 rotational systems, generally know their positioning on the court, and only occasionally need direction from teammates.
• A typical player can execute most skills (hitting, blocking, setting, passing, digging, and serving), but the results may be error-prone.
• Players may have some skills that are stronger than others as they specialize.
• Players at this level should be able to run plays with good passes and can typically get a kill on an open net.
• Players at this level should be able to play in more than one position if their team needs it
