PBISS International School

We deliver early years, primary and secondary education to children living on the island of Koh Samui

Our school’s vision has been to serve the needs of the local community. While we have grown as a school, we still hold true to our original values of providing an international education with a Thai heart. PBISS is a school that focuses on academic success, individual growth and emotional development. In 2021, the school welcomed new leadership, a team of Cambridge alumni and other top university

graduates, all with a passion for educational excellence. With this positive change, our Cambridge X STEM+ curriculum was born.

Our Year 12 students have proudly donated the proceeds from the activities and projects they developed as part of their Business course to Pariah Dog Koh Samui.

Through this real-world learning experience, students applied their entrepreneurial skills by planning, creating, and managing their own projects, while using the proceeds to support a meaningful local cause.

Their donation will help provide food, medical care, shelter, and rehabilitation for rescued dogs. As Pariah Dog Koh Samui relies entirely on donations, every contribution helps give these dogs a second chance at a happier, healthier life.

We are incredibly proud of our Year 12 students for demonstrating that business can be a powerful force for positive change in the community. Thank you to everyone who supported their projects and helped make this donation possible. 🐶💙
