Why choose a Boarding School?

Boarding Schools offer amazing life experiences and educational opportunities, such as small class sizes, excellent academic standards and extracurricular activities. These tangible benefits will be even surpassed by the intangible facts of becoming mature, self-confident and well prepared for University life and beyond.

We asked some of the best boarding schools in the world why parents usually choose a boarding school for their children, and here is an overview of their main reasons:

1. International Education

Boarding schools propose internationally recognized curricula, diplomas, and an international community. Students, teachers, and other staff members come from all over the world.

2. High Academic Standards

The learning experience as a boarding student is very different than in a day school. Boarding schools usually have high academic standards and can offer more supervision and support to students. Students can receive support from teachers, supervisors, or friends at all times, which can lead to a higher success rate.

3. Extra-curricular Activities

Extra-curricular activities are an important part of a boarding school schedule. Students can usually choose from a wide variety of activities and sports, and explore new talents or perfect existing skills.

4. Character Development

Experiencing a life away from home will help children develop more self-reliance and independence from their parents than they could at home.

5. University Preparation

Top boarding schools have good connections with the best universities and offer guidance and support to their students in finding their path after they graduate.

6. Lifelong Friendships

Boarding school friendships are specially strong because of the proximity and the shared adventure to be away from home. Other students and the school team become a new family.

7. Language Immersion

Boarding schools provide the opportunity to be immersed in the language. Students can become fully bilingual when attending a boarding school.
