- Foster students' emotional development by recognising their feelings and sensitivity, and by building up their self-esteem and a positive outlook on life
- Build physical fitness through athletic activities and the encouragement of physical well-being
- Support the students in the development of their personality and philosophy of life, the ability to recognise and solve problems, social competence and responsibility, and their respect for others and the environment.
