Girls high school volleyball playoffs typically begin at the conclusion of the regular season in late October or mid-November. Girls volleyball is a fall sport in most states, with the postseason completed over roughly a three-week period.
The postseason typically begins with district play, where teams compete against predetermined others in close proximity. Winners advance to face champions of other districts in regional play. Teams that make it out of regionals can proceed to advancement through the quarterfinals, semi-finals and finals.
