XIS works with an American based curriculum for the sixth through twelfth grades (about 12-18 years of age). Smaller class sizes of 15 students or less allow for both individual instruction and research into topics of student interest. XIS secondary teachers are dedicated to their students and bring enthusiasm to their specialties.
The school focuses on preparing students for entrance into American universities. Classes are targeted towards fulfilling credit requirements and providing a solid knowledge base for future learning. The credit system allows for a year by year rotation of study available within a subject. Thus, when a student graduates from XIS, he or she will have been able to study biology, chemistry, physics, and even anatomy in the sciences.
This broad range of study provides students with a strong platform from which to understand others and successfully interact with the world.
