Scottish rugby union system

The Scottish League Championship is the annual domestic league structure competed for by over 150 clubs at both national and regional levels.

Prior to restructuring in 2010, there were six national leagues - three divisions in the Premiership, and three in the National League - above the Regional Leagues. Further restructuring before the 2014-15 season scrapped the regional Championship A & B leagues which sat below the National League for two seasons. The current structure is:

• The Premiership: 10 clubs, top four compete in a knock-out play-off to decide the Premiership champions, bottom team relegated and ninth-placed enter promotion/relegation play-off
• National League: 36 clubs in three divisions:
  • Division 1: 12 clubs, winners promoted, runners-up enter promotion/relegation play-off, bottom two teams relegated
  • Division 2: 12 clubs, winners and runners-up promoted, bottom two teams relegated
  • Division 3: 12 clubs, winners and runners-up promoted, bottom three teams relegated to the appropriate Regional league
• Regional Leagues: 3 Regions (Caledonia, East and West) who organize their own league structures (though top divisions normally consist of 10 clubs), with the winners of each region promoted

The Scottish Cup was introduced in 1995 as a complementary knock-out cup competition. Though the structure of the cup has been changed numerous times it is currently contested by all National League clubs in the first round, with Premiership teams being added in the second and third rounds. The main cup competition is supplemented by regional shield and bowl competitions which all culminate in a 'Finals Day' at Murrayfield Stadium.

During the 2006-07 season an extra cup competition (The Scottish SuperCup) was introduced to replace the loss of fixtures in the Premiership due to league restricting. With the reversal of this restriction the following season the cup became redundant and was abandoned after a single season.

For the 2009-10 season a new cross-border tournament was introduced, the British and Irish Cup which would contain semi-professional clubs from the four home nations. Originally Scotland was represented by three sides but with restricting this has increased to four, who are determined by final positions in the League Championship.
