RBIS Open Days We can't wait to welcome you to one of our Open Days in October 2022. They're the perfect way to get a feel for RBIS International School and the excellent student experience we have become known for. Coming to an Open Day will help you gather all the information you need to help you make the right choice for your child. You will have the opportunity to explore our range of subjects and programmes by chatting with our Heads and current students, tour our range of facilities and learning spaces, and view the tranquility and serene environment the school offers right in the heart of Bangkok.
