Welcome to the High School at GSIS.

The high school division provides an internationally-based educational curriculum. The curriculum meets the needs of students planning to attend North American and international colleges and universities after graduation. GSIS is also a candidate school for the academically rigorous International Baccalaureate Diploma Program.

GSIS prides itself in providing an academic program within a nurturing and caring Christian environment where students, teachers, and parents work as a close knit community for everyone’s success. The student to teacher ratio is low, thus allowing for more student-teacher interaction and assistance. Assessment for and of learning is standards-based and emphasizes understanding and student achievement.

GSIS encourages educating the whole child, and to those ends offers a myriad of athletics and activities.
