THSI High School focuses on preparing students for university studies and their lives beyond primary and secondary education. Coursework can be intense, and class sizes are small to enable teachers and students to work closely together.
THSI High School offers an intensive college counseling program to help students discover their passion and areas of academic strength. See College Counseling for more information.
High School students also take on a leadership role in the development of the community life and traditions of THSI. These students lead the school governance structure through the Student Council.
THSI Middle and High Schools have a full-time counseling staff to assist students in managing the challenges of these years.
