ISSOS is a summer school unlike any other, we guarantee you will have a summer you will never forget and make friends that will last a lifetime.
You are with us during your summer holiday, so while you will still be learning lots in your classes we believe that education doesn't have to be boring, and we are confident that you will have just as much fun in your classes as you will when you're taking part in the activities programme or visiting a nearby city on one of our cultural trips.
How ISSOS makes your summer memorable
Every day at ISSOS is full of learning, discovery, and new friendships from around the world. Students are welcomed by a dedicated Group Counselor and begin by settling in, meeting their Groups and Clans, and starting classes.
By week two, friendships are strong, and students enjoy classes, evening events, excursions, and cultural trips.
In the final week, they prepare for showcases, tournaments, and end-of-session traditions like the Highland Games and final night dance. Students leave with lasting memories, confidence, and friendships.
ISSOS is different from other summer schools for a number of reasons:
A friendly, welcoming community where every student is known by name
A maximum of 150 students per session for a genuine family atmosphere
Ideal 3-week summer school programme length gives students time to make real progress in their learning, build confidence, and form lasting friendships
A perfect balance of academic excellence, creative enrichment and personal development
Carefully chosen staff who are experts in their subject and passionate about teaching
A safe and supportive environment, with all staff living on campus
A truly international mix of students – native and non-native English speakers always learn together
All inclusive programme fees, meaning there are no additional costs for trips, meals, activities

Student and Parent Spotlight
Hear what our students and parents say about ISSOS
Lucy
St Andrews
“Our daughter attended St Andrews, and she couldn't have had a better experience. It's no exaggeration to say that she was happy from the moment she arrived until the moment she tearfully left! This was especially reassuring for us, as she was visiting all the way from Canada and felt quite anxious before going. As parents, we highly recommend this program."
Saif
Cambridge
“I attended Cambridge and St Andrews, my first time at ISSOS and any camp. It was life-changing—I met my best friend, gained independence, and discovered more about myself. By summer’s end, we’d already planned to meet again. Thank you to the ISSOS Family for an unforgettable experience!”
Lowa
St Andrews
"Truly the experience of a lifetime! I went to St Andrews and had so much fun. The Leadership class and electives were really engaging, and the teachers and counselors were both professional and welcoming. Excursions and activities were incredible, and I met friends from all over the world who I hope will last a lifetime. Thank you ISSOS—I’ll never forget this summer!"
Maddy
Cambridge
“I had the time of my life at ISSOS. It boosted my confidence, helped me grow, and introduced me to amazing people who inspired me to be my best self. The classes were engaging, the diversity was incredible, and I loved the day trips and evening activities. The counselors were always supportive. Huge thank you to ISSOS—I’d do it all over again!
