ISO offers a wide range of extra-curricular activities for its students. Our intention is to attempt to provide each student with a chance to develop an area of interest, and to enhance their experience of school life overall.

All students are wholeheartedly encouraged to take this opportunity of beginning or pursuing an interest that lies outside the academic life of the school. Extra-curricular activities provide students with the chance to expand their horizons, and good universities throughout the world are always seeking students who have a breadth of experience.

The program is divided into 3 sessions, autumn, winter and summer and runs Monday to Friday, after school time from 15.00 to 16.00 for children aged 4 to 11.The activities offered include sports, performing arts, science, chess and board games, modern foreign languages, music and debating as well as special- interest clubs and extra lessons.

ECAs cover a wide variety of activities organized by teachers. In addition, there are ECAs offered by external coaches. These include karate, tennis, swimming, basketball, young engineering, BIG personality, aikido, cooking & nutrition activities and playing musical instruments. A full list is available each term on the school website and the registration process is well explained to parents at the beginning of the academic year. Some ECAs have an additional charge.
