  • One of Turkey's most prestigious K-12 schools, run by the non-profit Vehbi Koç Foundation on a 151-acre campus near Tuzla on Istanbul's Asian side.
  • Bilingual Turkish-English with optional French, German or Spanish. From end of Grade 10, students choose between an IB Diploma track and a Turkish national-curriculum track.
  • Reputation in Turkey is strong and stable. forum threads on Turkish university admissions list Koç alongside Boğaziçi and METU as the schools and universities students aim for; one student wrote "Koç okulu (zengin değilim, bursluyum)" ("Koç school, I'm not rich, I'm on scholarship"), reflecting that more than 400 of 2,200 students are on financial aid.
  • University outcomes drive much of the parent appeal. Around half of graduates progress to overseas universities including Cambridge, Harvard, Yale and MIT.
  • Open-web qualitative parent voices are thinner than the brand suggests; most online discussion is from current and former students or admissions-focused parents rather than long-form parent reviews.
