When you graduate from the IB, the study skills you gain and the maturity you develop in terms of taking accountability for yourself and your academics are invaluable. I built a foundation of what it means to study, what it’s like to have a plan, and what it's like to think forward.

The general culture that ISB gives you, to know a little bit about everything, is unmatched. I will have regular conversations with high-level business school students, and they will discuss the things they have just learned. I’ll be struck by the fact that it’s something I learned in tenth grade at ISB. It’s such a broad, deep education that really covers everything. It’s just a different level.

Academically, ISB prepared me exceptionally well. When I arrived in college, I had already encountered a significant amount of the content, which had been explained clearly by my teachers. The preparation for the Bac was preparation for college in general. It’s just what you do at ISB every week.

Our children have attended 4 schools in 4 different countries and ISB has been the best at welcoming them, and making sure they were happy and well integrated to be in a good position to learn and reach their dreams.
Teachers are the best at pushing the students beyond their limits. Students not only learn but take initiatives and demonstrate that they are already our future leaders.
Very pleased that both my children received their education at ISB.
