International Student Program

In 2014, Bishop Guertin High School welcomed its first group of international students. We never anticipated the wonderful and enriching experience it would be, not only for our students from across the world, but our entire BG community. We strongly feel that opening our doors to a more diverse student body speaks to our mission and goal for whole-person formation. Exchange and diploma students from Spain, Italy, Chile, Cambodia, Germany, South Korea, Mexico, China, Sweden, Vietnam, Finland, and more, have added to the vibrancy of the school and are such an integral part of the fabric of BG. We can’t imagine The Nest without them.

“Bishop Guertin offers a challenging curriculum and has a great atmosphere. If you try hard in your classes and to make friends, you will do well.” 

-Younggyoun ‘David’ Moon ’18, South Korea, Diploma Student

“The teachers at Bishop Guertin care about you, and they use many different teaching methods. The classes are engaging and the teachers are always willing to help you succeed!”

-Ana Campos Escalante, Mexico, Exchange Student

“My host family has been incredibly welcoming to me this year! They have provided me with the opportunity to really understand American culture and the lifestyle in New Hampshire. We like to have conversations about our cultures and to better understand one another.” 

-Ying On ‘Erica’ Chan ’20, Hong Kong, Diploma Student
