The project 'Developing key students' competences and strengthening self-esteem through their personal development' focuses on the development of key competences among students as an important element of preparing them for adult life. This project involves secondary schools (mainly vocational and technical schools) from Greece, Portugal, Cyprus, Lithuania, Spain and Poland. The proposing organization is located in Poland. Six actions are planned related to learning, teaching and training, including the first meeting in Poland, in which two teachers from each school will take part. Together, it was determined how important key roles in the teaching and learning process are key competences, while the project group agreed on the fact of struggling with problems resulting from the lack or insufficient implementation of key competences in the youth education process. Therefore, each of the partner schools indicated the most important problems that their students are facing during education. These problems can be divided into three main groups of key competences: social competences, mathematics and technology as well as language skills. Among social competences, partner schools and the applicant school exchange low self-esteem, lack of faith in one's own abilities, low ability to work in teams and lack of self-presentation skills. The main difficulties associated with mathematics and technology skills result from poorly developed creative thinking, low mathematical and IT competences. When it comes to language competences, students struggle to express their thoughts and opinions in their mother tongue and foreign languages.In addition to the emerging educational difficulties, each partner school has identified methods, tools and educational and upbringing programs that function in their facilities and contribute to the improvement of the quality of learning outcomes and develop key competences. Among these tools are tutoring tutoring, getting to know and working with such applications as: ONMAT, KAHOOT. EDPUZZLE, information and communication technologies, implementation of the STEM system combining natural and engineering subjects, workshops developing creativity, parental education program S.S.I.A preventing early termination of education and workshops with the trainer of self-presentation and rhetoric.The main objective of the project is to exchange good practices between teachers, in the first place taking part in particular stages of the project and then spreading the newly acquired skills among the schools' own communities and schools in the region. Each school will equip teachers who take part in the project with appropriate theoretical and practical preparation for further implementation of the method and tools for working with students. The products of the project activities are to be instructional videos, educational materials and improving the effectiveness of teaching in the field of science and foreign languages.
