Impro liga is now one of several complementary projects run by the Improvisation Society, and takes the form of a competition in short form improvisation for schools and other groups from the regions. To date, the series has involved over 100 successful shows at KUD France Prešeren Arts and Culture Association and resulted in a number of guest performances across Slovenia and abroad (Berlin, Vienna, Seattle, Graz). Impro liga competitions have also been presented at different national festivals, such as Lent Festival, Ana Desetnica International Street Theatre Festival, Sanje ('Dreams') Festival, etc.
Since 2005 Impro liga monthly organises the so called "Exhibitions" programme which presents non-competitive evening-length improvisations that include members of different impro groups and are based on thematic proposals from the audience. In addition, Impro liga also organises improvisational theatre workshops for youth and adults.
