A field hockey match consists of four quarters, usually 15 minutes each, and begins with a pass back (a non-defended pass from one teammate to another at mid-field).
A goal is scored when a player hits the ball in between the goal posts and over the line from within the 16-yard area. The ball must be struck with the players stick and any use of the body will be called as an infringement.
Goals can be scored from penalty corners which are awarded when a foul is committed in the 16-yard area. For a penalty corner, the defending team lines up on their goal line. The attacking team must all be outside the 16-yard area when one player hits the ball to them from 10 yards of either side of the goal line. As the ball is played back, a team mate stops the ball before another strikes at the goal. Two umpires on the field officiate the match. An additional umpire may sit at the scorer's table. The ball must be passed or dribbled down the field with the flat side of the stick. A goal is scored when an attacker strikes the ball into the goal from within the striking circle. Players may not shield the ball using their body or stick. All players must have an equal chance to play the ball.
