The main difference lies in admission criteria. BIS Zekeriyaköy is a private school that educates Turkish citizens, while BISI is an international school that, by law, accepts only students holding foreign passports.

The school follows the Turkish Ministry of Education curriculum. To support bilingual development, students receive intensive English instruction delivered by native English-speaking teachers.

The Zekeriyaköy campus offers education at Pre-Primary, Primary and Middle School levels.

Graduates of BIS Zekeriyaköy develop an advanced level of English proficiency and continue their secondary education well prepared, supported by the school’s international environment.
