"The implementation of the project "" Increasing Competitiveness of Graduates in the EU Labour Market via Bilingual Vocational Education and Strengthening Entrepreneurial Skills in Fictive and Real Companies"" has contributed positively to the development of secondary school pupils' professional traineeships and the professional development of teachers of vocational subjects. The primary objective of the project was to create conditions and to realize the internships of our pupils in foreign companies, taking into account the various specificities of the study fields (Business Academy, Economic Lyceum and Public Law Activities). Pupils gained the possibility of their professional involvement in private and public sector organizations. This has led not only to their deeper socio-economic integration but, above all, to the effective interconnection of professional and linguistic competences. The experience, knowledge and skills acquired by pupils abroad will be of great use to them in their employment or in further studies at college. The secondary objective of the project was to create conditions for teachers to improve the quality of vocational education at our school and to adapt to the requirements of the international labor market. The project provided an important reflection of the teacher's work, brought inspiration into further pedagogical activities, and enabled teachers to get acquainted with the differences in the international labor market. Foreign mobility of pupils and teachers took place in two runs. Firstly, in 2017 mobility from Ireland (a total of 15 pupils and 2 teacher mobility - professional development of workers) was carried out, followed by mobility in Germany (4 pupils and 1 accompanying person), Spain (4 pupils and 1 accompanying person) Great Britain (a total of 12 pupils and 2 teacher mobility - professional development of workers). Pupil mobility was organized as a three-week and teacher mobility weekly. Selected learner mobility learners have theoretical knowledge that entitles them to practice in their fields of study, command a foreign language (English, Spanish, or German) at A2-B1 level and the practical knowledge and skills they have gained during the compulsory practice of studying at our school. The work placement program was pre-arranged well in advance and the practical work placement of our pupils in professional practice abroad was agreed with all the recipient organizations. In the case of teacher mobility, it was a comparison of the education systems, the specifics of the international labor market, or the familiarization with the activities of companies that were oriented towards international trade. All these aspects have been taken into account when negotiating conditions with beneficiary organizations, as well as ECVET certification."
