The Scottish National League Division Three (known as Tennent's National League Division 3 for sponsorship reasons) is the fourth tier of the Scottish League Championship for amateur rugby union clubs in Scotland.
Geographical Location
The Scottish National League Division Three comprises the teams from both South, North, East and West teams located across Scotland.
Until 2011, the division was the sixth tier of amateur club rugby in Scotland. For season 2011–12, league reconstruction reduced the number of nationwide leagues from six to two and the division ceased to exist; however, further changes in 2014–15 increased the amount of nationwide leagues to four, and with it the National League Division Three name returned.
In 2022, the number of teams was increased from ten to twelve.[1]
The top two teams are promoted to National League Division Two and the bottom three teams relegated to the appropriate Regional League – Caledonia, East or West – depending on their geographic location. The winners of the top division in each regional league are promoted to Scottish National League Division Three.
