Teams
As finishing in one of the two last positions during the two previous seasons, Siarka Tarnobrzeg lost its right to participate in the PLK. However, the club was invited to join the league.

As champion of the previous I Liga, Miasto Szkła Krosno was promoted.

After the ejection of Śląsk Wrocław, the league was played by 17 teams. The intention of PLK is to reduce the number of clubs in the PLK to 16 and to eliminate contracts by introducing regular promotions and relegations. For this season, three teams will be relegated to the I Liga.
