RBIS High School Diploma
The RBIS High School Diploma is a flexible and personalised pathway designed for students who benefit from a broader, more balanced programme of study. Certified by Thailand's Ministry of Education, it is recognised for university admission in Thailand and accepted by many universities and foundation programmes internationally, subject to each institution's entry requirements.
Students build a personalised programme by choosing five subjects that match their strengths, interests and future aspirations. This flexibility enables students to pursue a curriculum that supports their individual goals while maintaining a broad educational foundation.
Unlike more specialised programmes, the High School Diploma offers greater flexibility through a broad curriculum with internally assessed coursework, allowing students to progress at a pace that suits their learning style and strengths.
Beyond academics, the programme develops the knowledge, skills and character needed for future success. Students take part in our Leadership Programme, community service, Work Experience Week and life skills education, including financial literacy, time management, communication and personal development. Students also benefit from integrated IELTS and SAT preparation, equipping them with the qualifications and skills needed for university applications in Thailand and internationally.

Student Success Stories
Kenny
Studying Law at the University of Essex
I graduated from RBIS International School in 2023 with a High School Diploma. During my time at school, I discovered a lot about myself. RBIS taught me the value of hard work and staying on track with my assignments, even in the face of challenges. I am grateful for the experiences and memories I have gathered at RBIS; they have contributed to shaping me into a more confident and self-sufficient individual.
