After the COVID-19 pandemic in Scotland, only 24 teams entered the National Competition and so a third league was not required.
An annual tournament pitted the top teams from each district against one another and this eventually formed the basis of a national league system.
The 1974–75 season was the initial steps to form 'official' national leagues in 1975–76.
Participating clubs played for league placement for next season.
However, due to the increased number of entrants into the national leagues a sixth-tier was required again.
