5. Collège du Léman International School
There are endless amounts of awesome things about the most expensive boarding schools in the world in 2017-2018. What’s cool about Collège du Léman is for one, the fact that the starting age at which they offer such a high-quality education to is 2-years-old. Most of these schools do not offer such an opportunity to preschoolers, let alone elementary aged children. The cost for just day students, however, is nothing compared to the $94,649 tuition they are asking for boarding students. Although, they do offer a nice discount if you choose to enroll multiple children. Another sweet deal they got goin’ on is their charity program. High school students get to run these events and even get to travel to Africa to see how they, personally, are making a difference in the lives of children who are less fortunate than them. Pretty cool!
