Summer school 2021

Welcome to Summer School in an English-speaking environment!

We are pleased to announce that we have summer school this 2021! 



Being multilingual is an edge in a globally expanding society.  Students need to learn a second language as early as they can. Thus, improving and  practicing your children’s English communication skills during the summer vacation is a great move for their future.

The essence of learning is in life application! Even if you study  English, its effectiveness is reduced when there is no environment to use it.

The OIS Summer School Curriculum is designed to help students improve their English skills through life and society. Daily conversations in English, actual immersion and engaging activities await learners who would like to brush up both their conversational and academic skills.

We hope you will join us again this year to learn, play, and improve your children’s English skills.
