In NSSA discipline, targets are released in a combination of singles and doubles, adding up to a total of 25 targets per round, from the High and Low trap houses on a fixed trajectory and speed. Variety is achieved by shooting round the seven stations on the semicircle, followed by an eighth station, located between stations one and seven. Scoring is on the basis of 1 point per target killed, up to a maximum of 25.
In English skeet (by far the most popular of the skeet disciplines), the gun position is optional (i.e., premounted or outofshoulder when the target is called) and the targets are released immediately upon the shooters call.
In Olympic skeet, the targets travel at a considerably faster speed, the release of the target can be delayed up to 3 seconds after calling and the gundown position is compulsory. There is also an eighth shooting station, midway between the two houses.
