The "European professional competence in plus!" project was prepared along with the partners: VITALIS Betreuungsgesellschaft für Modellprojekte mbH (Germany – the internship was served by the students from the fields of: mechanic and electronics technician) and EUROPROYECTOS LEONARDO DA VINCI S.L. (Spain – the internship was served by the students from the fields of: IT technician and organization of advertising techniques). The project was an answer to a range of students’ needs, such as professional/educational (including linguistic), social and personal ones. It was also an opportunity to level the obstacles connected with professional mobility through raising the linguistic competence (English/German/Spanish – mainly the professional vocabulary) and become acquainted with market requirements of partner EU countries (Germany, Spain). Substantive issues of the project were consulted with and reviewed by the cooperators of the school – companies: ZETO Rzeszów, WSK PZL -Rzeszów S.A., POSD Rzeszów, Echo-Fon System oraz CC-Metal. The main aim of the project was to acquire practical skills in the use of modern technologies and design tools associated with the field of their education as well as the development of soft and language skills by the ZST students throughout their internship. In addition, the participants used the graphic packages of utility and tool software, they learnt and applied professional terminology (English language), stimulated the development of interpersonal skills and shaped the pro-European attitudes, breaking down cultural stereotypes. The project was addressed to a group of the ZST students - Technical School No. 9 in Rzeszow (aged 17-20) enrolled in the professions: IT technician - 16 participants, mechanic technician - 14 participants, electronics technician - 14 participants and organization of advertising techniques - 14 participants. The participants were divided into 4 groups, each taking into account the profession. There was a tutor departing with each group – a seconded teacher of the ZST Rzeszow. The internship for each group lasted 3 weeks (15 working days of classes). The topics were related to the following areas: programming web sites, computer typesetting and installation of video materials, design and programming of printing devices in 3D technology and the use of modern design tools as well as CNC machine tools in the industry.
