The possibilities of co-financing the establishment and running of training schools in Poland under the Human Capital Operational Programme 2014-2020 were presented. The training offer for teachers was discussed and characterized in an exemplary project co-financed by the European Union: „Teacher Training School model in Niemcz and Osielsko" based on the expectations of teachers in the light of the pilot studies conducted on a sample of 52 people. Finally, recommendations for the organization of the training process for teachers were indicated.
