Prem Tinsulanonda International School is one of Thailand's most distinctive and highly regarded boarding schools, located in the scenic Mae Rim Valley north of Chiang Mai. Founded in 1997 and named after Thailand's former Prime Minister and statesman Prem Tinsulanonda, the school offers a British-based education from Year 7 through to Year 13, with full boarding from Year 7 and day places available for local families. At Sixth Form, students can choose between A-Levels and the IB Diploma.
Prem occupies a breathtaking 80-acre campus in the foothills of the Himalayan range, featuring world-class facilities for academic, sporting, and outdoor pursuits. The school has a strong tradition in outdoor education and leadership development — the Mae Rim Valley setting allows for trekking, rock climbing, white-water rafting, and community service activities that are integrated into the regular school programme. Boarding is at the heart of the Prem experience, and the school operates a fully residential community that fosters independence, resilience, and lifelong friendships.
Prem is CIS-accredited and produces exceptional A-Level and IB Diploma results, regularly sending graduates to Oxford, Cambridge, leading US universities, and top institutions in Asia and Australia. The school attracts students from across Southeast Asia and beyond who are seeking a prestigious, character-building British boarding education in an extraordinary natural setting. Prem is one of a very small number of boarding schools in Southeast Asia that genuinely competes with UK boarding schools on academic outcomes and community culture.
