One of the strengths of the School is the diversity of extra-curricular activities available to the students. Much of the confidence and the wide range of interests of our students are derived from the list of activities available to the youngsters here. They are expected to attend at least one activity a week, though many sign up for two or three.

Prominent in the activities are the range of music and drama on offer. The International Youth Award and the Interact Club are well-supported and active.

The spiritual welfare of the boys and girls is provided for in the activities of the Buddhist Society, Christian Fellowship and the Islamic Society, all of which have a busy programme. 

Students at KTJ have access to a marvellously wide range of sports. The facilities are extensive, including  tennis and squash courts, basketball courts, a swimming pool, rugby, football, hockey and cricket fields, and dedicated areas for handball, netball, softball and volleyball.
