Galatasaray Lisesi

What Galatasaray Lisesi does

Galatasaray Lisesi is a public state high school (devlet lisesi) located on İstiklal Avenue in the Beyoğlu district of Istanbul, Turkey, institutionally affiliated with Galatasaray University and operating under the supervision of Turkey's Ministry of National Education (Milli Eğğitim Bakanlığ). The school traces its lineage to the Galata Sarayı Enderun Mektebi (Galata Palace Imperial School) established in 1481 and was formally established as Mekteb-i Sultani in 1868; it currently enrolls its 160th cohort. It offers bilingual secondary education (grades 9-12) in Turkish and French, certified by the French Ministry of National Education through the FrancEducation label, and admits students competitively via Turkey's national LGS (Liselere Geçiş Sistemi) high school entrance exam. The school is residential, offering both boarding (yatılı) and day (gündüzlü) student tracks with published annual installment fee schedules.

The institution's core product is its academic and extracurricular program, supported by specialized laboratory and workshop facilities including the BT Laboratory, Biology, Physics, and Chemistry Laboratories, the SOBIT science and technology education laboratory, and Robotics, Music, and Visual Arts Workshops. Supporting infrastructure comprises four libraries (Tevfik Fikret, Haldun Taner, Sedat Simavi, Yiğit Okur), three sports halls (Faik Üstünidman, Selim Sırrı Tarcan, Behçet Gücer), ten-plus student clubs (Mathematics-Science-Technology, Aviation and Space Sciences, French Theater, Music, Social Responsibility, etc.), and student-produced digital publications (Galeta newspaper, Yalım magazine). The school operates a proprietary KVKK-compliant online appointment system (GSL Randevu Sistemi) for managing prospective-family campus visits and runs an annual Open House (Tanıtım Günleri) program. International programs include an annual student exchange with Nancy Henri Poincaré Lycée in France, Erasmus+, and Europe@School.

Galatasaray Lisesi's business model is fee-based for tuition and boarding, published annually via installment schedules for the residential and day tracks, supplemented by state funding through the Ministry of National Education. Revenue figures are not publicly disclosed. The go-to-market is non-commercial: admission is administered centrally by the MEB through the LGS exam, with no direct sales motion; the school's marketing channels are its official website (gsl.gsu.edu.tr), its X/Twitter account (@gslise), the annual Open House, and earned media coverage of student olympiad and university-placement achievements. Documented student outcomes include multiple gold medals at the International Mathematical Olympiad (IMO 2025), ISEF World 4th place in Chemistry (2026), Balkan Mathematics Olympiad medals, and full-scholarship admissions to MIT (2026). The school is embedded in a broader Galatasaray institutional ecosystem comprising Galatasaray University, Galatasaray Spor Kulübü (Sports Club), Galatasaray Education Foundation (GEV), Galatasaray Alumni Association, and Galatasaray İlkokulu. Leadership is currently provided by Principal Prof. Dr. Mustafa Reşat Dabak.
