Klasa A represents the seventh level of the Polish football hierarchy. Teams promoted from Klasa A move up to the liga okręgowa, whilst relegated teams descend to the Klasa B leagues.
The exceptions are Klasa A in the Podlaskie Voivodeship, where it is the lowest tier of the game (no Klasa B), and in the Greater Poland Voivodeship, where it is the eighth tier of the football hierarchy, due to the existence of V liga in this region.
History
In 1920–1927, Klasa A was the highest level of regional competitions, class A champions met in the finals of the non-league Polish Championships. In 1928, the league joined the Polish Football Association and Klasa A became the second tier of the competition – its champions were promoted as a result of multi-stage play-offs. In the 1930s, district leagues were gradually established, thus class A became the third level of the competition. It regained its importance shortly after the Second World War in 1946–1947, when the non-league Polish Championships were played again. In the following years, the successively created or liquidated leagues (second, third, fourth, fifth) resulted in the fact that Klasa A fell in the hierarchy of games in Poland.
