Jeziorak played in the second division for five years and spent multiple seasons at the third level of Polish association football, and currently sits in the IV liga Warmia-Masuria.

In 2014, a new association, initially called ITR and later renamed to ITS Jeziorak, which continues the traditions of the club established in 1945, was founded.

In the 1999–00 season, the two groups of the second division were merged to create a single II liga that numbered 24 teams.

Jeziorak, having won its group of the fourth division, participated in playoffs against Unia Tarnów winning in a penalty shootout[6] and gaining promotion to the new II liga.

However, continuous financial problems resulted in the team being relegated and then, withdrawing from participating at the fourth level in 2012.

[1] Jeziorak spent the following two seasons (2012–13 and 2013–14) in the regional league, the sixth level of association football in Poland.

In 2014, the team started anew by joining the Klasa B,[1] which is the eight division - the lowest level of association football in the region.

The club's most notable result at the central level of the Polish Cup was achieved during the 1994–95 season.

[1] In the fall of 1994, before being promoted to the second division, Jeziorak won against Polonia Chodzież (third division at the time) in a penalty shootout in the first round, proceeding to win against Stomil Olsztyn (recently promoted to the top tier of Polish association football) in a penalty shootout in the second round.
