These are the basic definitions of rankings or divisions for teams, their associated skills, and rules that apply:
"Open"
This division consists of primarily "AAA", "AA", & "A" players. Typically, these players have had intensive training for national tournament competition at the collegiate and semi-professional levels and have obtained a regional and/or national ranking. These players consistently display advanced ability in most specialty areas, along with top caliber development and execution of skills. These players have developed power and/or consistency as a major weapon. These players can vary strategies (double or left & right outside blockers) and styles of play in a competitive situation and hit dependable shots (middle attacks, high-line roll shots, short cross-cut shots, etc.) in a stress situation. All rules apply.
"A" (4 points for each player)
These players consistently display advanced ability in either offensive skills (spiking, serving, setting) or defensive skills (passing, digging, blocking) to compete as a specialist and have sufficient ability to execute the dynamics of power volleyball. Also, these players do not meet the guidelines for any higher rating. These players have begun to master the use of power shots and are beginning to handle pace, have sound footwork, can control depth of shots, and are beginning to vary game plan according to opponents. All rules apply. A team must have more than 12 total player points to compete in "A" division.
"BB" (3 points for each player)
These players have achieved improved ball control, dependability with directional control on moderate shots, and are developed in more than one specialty area. These players exhibit more aggressive net play, have improved court coverage, and are developing defensive strategy. All rules apply. Any team that has won one "B" league season or tournament may move up to this division. A team must have more than 8 total player points to compete in "BB" division, but they must not exceed 14 points.
"B" (2 points for each player)
These players have a higher-level specialty area (setting, hitting, passing, blocking, or serving). These players are more skilled at consistently placing the ball in areas and have improved court coverage. All rules apply. A team must have more than 4 total player points to compete in "B" division, but they must not exceed 10 points.
"C" (1 point)
These players know the rules and are moderately proficient at keeping the ball in play. These players are moderately proficient at spiking, setting, or passing, and are learning placement and defensive anticipation. All rules apply, except all hand-sets are legal (no hand set calls), as long as the sets are not over the net (even if legal). A team must have 7 total player points or less to compete in "C" division.
"Novice"
New players. These players are not familiar with the rules, are primarily concerned with keeping the ball in play, and need more on-court experience. There will be a coach or referee to make the calls and keep score. All rules apply, except all hand-sets are legal (no hand set calls), as long as the sets are not over the net (even if legal). The coach or referee will help correct the following rules after the play: foot faults, setting the serve, "underhand" hits with an open hand, open one-handed pushes or "slam dunks" (must use knuckles), double hits, net faults, or colliding with a player under the net.
