IB Diploma Results

OIS students consistently beat the world average points score with their IB Diploma results, even though we are a non-selective and inclusive school. We also offer scholarships each year, with priority going to young people in the local Oeiras area.

Our philosophy to nurture individual excellence means no child is left behind. As a result, our graduates go on to attend some of the best universities in the world. Visit our University Destinations page to see just some of the places for which our alumni have received offers.

From the teachers, the assistants, the students and the entire staff of OIS – there has always been a nurturing yet academic environment. A place I call school which feels like a second home. The teachers continuously strive to bring the best in each and every student, day after day. I have felt supported and safe. Entering Med School in Germany would not have been possible without the help of OIS. The IB program at OIS has helped shape me into the young adult I am today. Ever determined, ever grateful.
Vitória Ahern – Graduated 2019-2020

At OIS, we are motivated by our students’ consistently high IB Diploma results. Every year since OIS opened, the school has achieved an average point score that is superior to the worldwide average. What’s more, in six out of nine years, we have had students who have achieved grades of at least 40 out of the maximum 45. In 2019, three of our students scored 41/45 or higher. You can see our results since 2012 in the IB Diploma results table below.
