International School of the Sacred Heart

Founded in 1908, the school is a Catholic institution guided by the mission of the Society of the Sacred Heart, focusing on the development of the whole person—intellectually, spiritually, emotionally, and physically. It emphasizes the "Sacred Heart Goals," which prioritize love, gratitude, generosity, compassion, and forgiveness, while fostering global citizenship and leadership in girls.

The school offers an all-English, college-preparatory curriculum from Kindergarten through Grade 12. High school students have access to 23 Advanced Placement (AP) courses. The academic program incorporates a unique values-based curriculum, with specialized instruction in STEM, robotics, visual arts, music, and drama.

Graduates consistently outperform global counterparts on Advanced Placement (AP) exams, earning university credits that facilitate matriculation to prestigious institutions in the US, UK, Japan, Australia, Canada, and worldwide. Alumni pursue diverse paths, including top-tier universities and specialized art and design schools.

The school provides a student health office with a full-time, bilingual licensed nurse to assist with student well-being, injuries, and medication management. Pastoral care is integrated into the school experience to support the social-emotional, spiritual, and psychological development of each student.

The school offers rolling admissions year-round for students from Pre-K to Grade 12. The process includes an application fee, and prospective families are encouraged to book a weekly school tour for a guided walkthrough and Q&A with leadership. Admission is open to international families and those seeking a diverse, English-speaking environment.

The school year typically runs from late August to mid-June. Key breaks include a fall break in October, a winter break from mid-December to early January, a mid-term break in February, and a spring break in March. High school graduation is scheduled for late May.

Located on a wooded campus in Hiroo, the school features a gymnasium, a mini-gym, a turf field, a futsal pitch, and tennis courts. Academic and creative spaces include science and technology labs, a robotics arena, ceramics and food technology labs, and multiple performance spaces with professional lighting. The campus also houses two libraries with over 34,000 volumes, a chapel, a cafeteria, and a student health office staffed by a bilingual nurse.

Students participate in a wide range of activities including student council, Model UN, debate, and various clubs. The school also offers an Extended Day Programme for childcare needs and hosts competitive athletic teams that participate in regional leagues like the Kanto Plain Association of Schools. Additionally, students engage in service-learning projects, such as a long-standing partnership with a school in Nepal.
