Our organization is applying for funding for a total of 11 mobilities in the Erasmus + Programme. The mobilities are related to general language courses and specialized language courses with CLIL in Germany, Great Britain, Italy and Latvia intended for the school management, teachers and teaching assistants. The acquired knowledge, experience and knowledge gained during the mobilities will be applied by participants in their home school in the system area and in direct work with students. Participants will compare the gained experience and use it in order to upgrade and optimize the methodological and didactic procedures. Language skills of teaching staff of the school will be increased through the European mobility activities and the offer of foreign languages will be extended, namely by the Italian language. Subsequently, cooperation with a school of similar type in Italy will be established, and therefore the international dimension of the school will be expanded. CLIL will be implemented in some subjects of the first stage classes and in selected history classes in the second stage classes in consequence of language courses specifically focused on CLIL. This will support the school strategy that strives for reinforcement of internationalization. Furthermore, students' language competencies in taught languages will be improved. Owing to the above, the possibilities of students on the European labor market will be improved.
