History 

The British International School Istanbul has been in existence for twenty five years, but the current proprietor took over in 2000. BISI is a split site school with a City Campus in Etiler for Pre School and Primary and a Forest Campus in Zekeriyakoy which covers students aged 2½ to 18. Over the last few years the school has demonstrated growth and development and continues to do so. Student numbers have increased and the facilities and resources followed suit. The Zekeriyakoy Campus was built and opened in 2006 in response to the growth in student numbers. In September 2017 the school expanded to include a new national school for children between the ages of 2 and 7 whose parents seek a Turkish education with an international flavour. It is anticipated that the new national school will grow year on year until it educates students up to Year 13. General Information
