Szentendrei Református Gimnázium has been operating since 1999. Since then it has been expanding and developing. The growing number of students and staff has posed challenges and made it indispensable to work on new means and feasible solutions. The knowledge and experience of our national and international partners have provided us with opportunities to learn and improve our institution. Our objective is to maintain the further improvement of our teachers' professional skills by cooperating with schools and attending courses. To know how to implement new methods which are closer to meet the needs of students, to bridge the digital gap between students and teachers is obviously necessary. To plan, maintain and build further ties with schools from Europe can serve the successful realization of the above mentioned goals. Managing our international relations has been a responsibility of the language teachers. The experience that these relations can work much more effectively if teachers of subjects other than languages can be involved was also gained in the Netherlands. The insufficiency of language skills and confidence of teachers have proved to be an obstacle to that. That is why the skills of three colleagues were planned to be improved at German language courses. One teacher took part in a French course and one in an English course. Two colleagues attended an ICT and museum pedagogy course in English. A Mathematics teacher who speaks good English took part in a course designed for secondary school teachers. Those colleagues were chosen who can be integrated into work on tasks of present Dutch-Hungarian and planned further German and French international relations. It was also important to have at least one representative of each school subject area among the participants. To improve the professional repertoire of another colleague teaching languages joined a summer course aimed at methodology in native English environment. The course helped acquire methods to improve intercultural competences to be able to prepare students taking part in student exchanges more carefully, prevent cultural shock and raise their awareness of intercultural learning. The completion of courses of all the nine participants enabled them to become acquainted with new pedagogical methods and to improve their motivation to get to know and in addition regularly use new ICT tools and applications. By the end of the school-year creating and using web2 and e-learning tools tailored for the needs of our school had become more widespread than last year. The school management awarded participants with credit points for their work as part of their mandatory education scheme. The process of the implementation of the project was continuously monitored with various evaluation methods such as interviews, self-assessment questionnaires, online feedback to ensure the realization as closely according to the plan as possible and the more efficient design of forthcoming projects. The experience gained in this project will be applied in designing the tasks to be done together with our German and French partners and some of the eight schools we met in Comenius School Partnerships and our twin schools in Transylvania.
