The Ultimate Choice for Global Families: Why BISI Remains the Leading International School in Istanbul

Choosing the right school is the most critical decision for any family relocating to Turkey. For nearly four decades, the British International School Istanbul (BISI) has been the definitive choice for the international community, offering an education that transcends borders.

1. The Triple Accreditation Powerhouse: CIS, COBIS, and MSA

BISI stands as a beacon of academic excellence, being the first and only school in Türkiye to hold a triple accreditation that covers every global requirement:

• CIS (Council of International Schools): Ensuring the highest international standards in protection, leadership, and curriculum.
• COBIS (Council of British International Schools): The hallmark of a premier British education outside the UK.
• MSA (Middle States Association): A prestigious American accreditation that validates our high school transcripts for top-tier universities in the United States and worldwide.

This "Triple Crown" ensures that whether your next move is to London, New York, or Singapore, your child’s education remains seamless and globally recognized.

2. A Purely International Community

BISI is a true international school. In compliance with Turkish regulations, we exclusively serve the international community. This creates a unique, diverse environment where over 50 nationalities coexist. For an expat child, this means an immediate sense of belonging among peers who share the same global lifestyle and transition challenges.

3. 39 Years of Excellence in Education

Established in 1987, BISI is not just a school; it is a legacy. For 39 years, we have been the first choice for diplomatic missions, multinational CEOs, and high-net-worth expat families. Our experience in managing the "transition" phase of moving to a new country is unmatched in Istanbul.

4. The Zekeriyaköy Advantage: Space, Safety, and Serenity

Located in the prestigious Sarıyer / Zekeriyaköy district, our campus offers what central Istanbul often lacks: Space.

• Spacious & Green: Surrounded by the Belgrade Forest, our students breathe fresh air in a secure, tranquil environment.
• World-Class Sports Facilities: From heated indoor pools to professional-grade football pitches and tennis courts, we prioritize physical well-being.
• Safe Haven: A gated, highly secure campus designed to give parents peace of mind while their children explore and learn.

5. Academic Pathways: From EYFS to the IB Diploma

We offer a seamless educational journey through the National Curriculum of England (modified for international students) and the IB Diploma Programme. This ensures that our graduates are prepared for top-tier universities worldwide, from the Ivy League to Oxbridge.
