The International School of Siena, established in 2010, is a private day school offering the International Baccalaureate (IB) curriculum from early years through to diploma level. Instruction is primarily in English, with Italian as an optional language.

The school is set in a 17th-century villa near Siena, a historic university town, and serves a diverse international student body. It does not provide boarding facilities, operating solely as a day school. Lunch and snacks are available on campus for an additional annual fee.

Extracurricular programs include a wide range of sports, arts, and cultural activities, along with local excursions. Campus facilities include classrooms, science labs, art and music studios, and sports areas.

Admission requires a completed application, academic records, proof of English proficiency, an interview, and an entrance assessment. Tuition fees vary by grade level, and additional costs include application and registration fees, meals, and other personal expenses.
