PBISS International School on Koh Samui began in 2005 and teaches students aged 2 to 18, following the Cambridge International Standards blended with a STEM+ approach, meaning science, technology, engineering, and math are built into every stage. The campus hosts a STEM+ Innovation Centre, a hub where students work on hands-on projects like 3D printing, laser cutting, and vinyl crafting, and even participate in events like the Theme Park Challenge alongside a STEM Expo. In the youngest years, children engage in activities such as robotics, hydroponic gardening, and even a STEM Farm, alongside learning with tools like balance bikes and Lego tables. Secondary learners move into Cambridge IGCSE and A-Level courses under a “Learning to Mastery” philosophy that emphasises thinking and creation, not mere memorisation. Located in Chaweng Noi on Koh Samui, the school brings together international education and a distinctively hands-on, STEM-infused learning experience.
