Oeiras International School and the Portuguese Rugby Federation have established an interesting partnership that allows our students to know more about the energy and charisma that characterizes this sport.


Prémio Infante D. Henrique / Duke of Edingburgh Award is an international social and individual development Programme, targeted to people from 14 to 25 years old. This initiative encourages its participants to be active citizens, with the goal of having a positive impact on society. This  will enable the participants to have lifetime learning experiences that will make a difference on themselves, on their communities and on the world.

The Programme exists in more than 100 countries and although the name can vary, its philosophy and basic principles are the same. Until now, more than 6 million youngsters have participated.
