The International School of Kuala Lumpur provides (silence) an exceptional education that challenges each student to develop the attitudes, skills, knowledge and understanding to become a highly successful, spirited, socially responsible global citizen.

I feel that adding a silence after the word “provides” creates the best tension. When you add a void after the provides, the audience might have a question in their head. The question that would pop into my mind is "the school provides what?" I think that question is the best void, and then after the reader finishes his/her pause they give the listener the answer by going on with their speech.
