Aljazari International School of Science and Technology, Istanbul

The visible review pool is small and sharply negative on recent dates.
A recent parent review wrote "none of the advertisements are true, the programs are designed to satisfy the parents rather than serve the students' interests", and added that administration warmth fades after the fees clear.
A student review called it "the worst school anyone would enter", flagging that the American diploma is not actually delivered and that teachers are routinely absent.
Older positive reviews praise the labs (robotics, chemistry, science, computers), the sports centre and swimming pool, and a multinational student body drawn from the Arab world, Russia, Iran, North Africa, China and Europe.
One earlier family from Lebanon called it their top choice among Istanbul international schools, but newer posts have walked that back hard.
Treat the pool with caution: small sample size, two clearly negative voices and a clear positive-to-negative tilt over time.
