British International STEAM School Istanbul
Boutique primary school in Etiler with triple accreditation (CIS, COBIS, MSA) - the only school in Istanbul to hold all three simultaneously. STEAM is embedded as a pedagogical approach throughout, with average class sizes of 8 and a teaching assistant…
In brief
The boutique city campus sister to BIS Istanbul, focused on early years and primary in Etiler with a Cambridge curriculum and a STEAM specialism.
BISS is the city-side feeder for the wider British International School Istanbul group, covering ages 2 to 11. The Etiler campus consolidated earlier Levent, Alkent, and Etiler sites into one location in 2017 and adopted the STEAM identity in 2022. The curriculum follows England's National Curriculum and the Cambridge framework, with English, Maths, Science, and Digital Literacy structured to Cambridge standards.
The student body sits around 80 children, which keeps the environment small and personal compared with the larger Zekeriyaköy senior site. Most BISS pupils transition into the BIS Zekeriyaköy primary or secondary campus after Year 6. Fees are toward the upper end of the Istanbul private school market, roughly 1.1 to 2 million TRY, which reflects both the small class sizes and the central Etiler location.

Reviews
- Online review pool for the STEAM-branded campus is very thin, separate from the better-known British International School Istanbul (BISI) in Sariyer.
- Most directory listings cluster the three British School Istanbul divisions (BIS, International, STEAM) and apply BISI's four-out-of-five rating to all of them; little STEAM-specific parent voice.
- The school's positioning sits around STEAM-led primary into Cambridge Lower Secondary and IB Diploma routes.
- Reddit thread for Istanbul international schools mentions BIS but does not distinguish the STEAM division.
- Confusion with BISS Istanbul (the Russian-curriculum school) and Tarabya British School flagged elsewhere by parents and teachers.
