The goals of the project concerning this grant application are to develop the bilingual department at the St. Nicolaaslyceum as well as support the development of the bilingual team (30 persons) regarding speech, listen and writing skills in English and CLIL-skills. Also, activities on internationalisation will be improved and extended by e.g. e-mail projects, and the development of the EIO-programme thereby meeting the CFER requirements. Furthermore, the departments of modern languages French, German and Spanish will cooperate with the bilingual department through involvement in EIO-programme, development of CLIL-skills and implementation of ‘doeltaal=voertaal’ principle. All participants are a member of the bilingual team and have been selected on a motivational basis. All teachers are certified either as ’eerste graads’ or as ‘tweede graads’. All participants will have their CLIL-certificate by the start of the grant period. Ten subjects will be taught in English and in most cases two teachers have been trained per subject so they act as each other’s buddies. The following activities and results are part of this educational project: 1) Intense course of the English language in order to meet the level of the Cambridge Advance Exam (speech, listening, writing), which will be completed with the CAE diploma by the end of December 2014; 2) The development of knowledge, skills and material at such a level that CLIL-skills could be shaped, which will be completed with a CLIL-certificate; 3) The development of knowledge, skills and material at such a level that the EIO-programme could be shaped, which will be completed with a CLIL-certificate; 4) Encouraging the development of a professional and pro-active attitude towards learning of the participants, thereby contributing to the bilingual team build. Furthermore, the points described above are part of the teachers trip Hilderstone (2014, including a certificate) and the teachers trip Cumbria-CLIL (2015, including certificate) which are both organised in the UK. Expected results are the improvement of the teachers’ level of English (CAE level) and the teachers’ abilities to support the pupils’ individual educational needs. Besides, the CLIL didactics will be improved too. The improvement of English as well as the CLIL-skills will contribute to the professionalization of the bilingual department which will be envisioned by the personal development plan and a positive assessment by the supervisors. The activities carried out will also contribute to the PR-activities, for example reaching future pupils. Also, the experience acquired will be shard through good practices inside and outside school as well as in our ‘Zuidas’ network. Furthermore, these activities will enhance the process of becoming a ‘TTO-junior’ school.
