St. Andrews International School, Green Valley, stands as a symbol of educational excellence nestled along the Eastern Seaboard, conveniently situated for the communities of Pattaya and Rayong. Our school thrives as a close-knit community, fostering a sense of family while also offering the depth and diversity found in larger institutions.

At the core of our educational philosophy lie three key principles: Eco-Literacy, Personalised Learning, and Holistic Education – nurturing the essence of the 3 Be’s: Be Adventurous, Be Brilliant, Be Happy. These principles not only guide our commitment to education but also empower us to cultivate well-rounded individuals who are ready to explore, excel, and embrace the essence of happiness.

Starting from our vibrant Early Years and Primary School, we create a nourishing learning environment that seamlessly blends the International Baccalaureate (IB) Primary Years Programme (PYP) with the English National Curriculum. This dynamic fusion enables us to provide an education that is globally attuned yet finely tailored to individual growth.

As students progress to our Secondary School, they undertake a transformative journey that encompasses IGCSEs in Years 10 and 11, followed by the IB Diploma Programme (DP) in Years 12 and 13. This comprehensive approach fosters active engagement, positioning students at the forefront of their educational journey and fully preparing them for higher education and beyond. Moreover, for students whose primary language is Dutch, our Dutch stream programme creates a supportive community, serving as a home away from home where students can thrive in an environment that truly understands and nurtures their linguistic and cultural needs.

Our commitment extends beyond the confines of the classroom. Rooted in community engagement, our students participate in meaningful experiences that deeply connect them with the local landscape, nurturing a profound sense of place. This integration of learning and community exemplifies our dedication to holistic development.

At St. Andrews International School, Green Valley, we offer more than just an education; we provide a transformative journey towards becoming compassionate, informed global citizens, shaping a brighter future where adventure, brilliance, and happiness naturally converge.
