ISSOS International

Since 2005, ISSOS has created safe, inspiring, and truly international summer schools for students aged 13–18. Each summer, we welcome young people from over 80 nationalities to our campuses at the University of St Andrews, Cambridge, and Yale, where they enjoy a unique mix of academic study, creative electives, and adventure.

What makes ISSOS different ?

A Global Community – Native and non-native English speakers are fully integrated, with no single nationality making up more than 10% of students. This ensures students improve their English while making friends from around the world.

All-Inclusive Fees – Cultural trips, three meals a day, insurance, ISSOS clothing, evening programmes, airport transfers, and more—everything is included, with no hidden costs.

Professional Teaching – Every subject, from Debate and Business to Tennis and Theatre, is taught by experienced professionals who deliver the highest standard across all classes.

Unique Campus Experience – With up to 150 students living on one campus, ISSOS offers a close-knit community. Thanks to exclusivity agreements, ISSOS is the only summer school operating on-site.

A Welcoming Atmosphere – Over 80% of students come through referrals, creating a warm, family-like environment where everyone feels at home from the start.

ISSOS offers more than a summer school—it’s a transformative experience where students gain confidence, independence, and friendships for life.
