Setting a new standard for international education in Phnom Penh

Established in 2017, ISS International Academy is one of the first schools in Phnom Penh to offer a blended curriculum based on both the Singapore Curriculum and the International Primary Curriculum (IPC).

“TGI identifies with the vision and values of ISS International Academy – a school where the learning environment is dynamic and creative. We want to inspire a new generation of globally competent citizens.”, says Mr Ronald Stones OBE, Founding Director, The Grange Institution.

This new partnership will bring in expertise from TGI to further enhance the education standards at ISS International Academy through curriculum and professional development.

Education that inspires globally competent learners

Located in the heart of the city of Phnom Penh, students enjoy spacious classrooms, a technology lab, futsal court and a swimming pool that provides a stimulating learning environment.

“We are excited for this partnership with TGI. With the depth of experience from their academic leadership and strong regional network, we will adopt best practices to continually improve the standard of education that we offer.”, says Mr. Wang Junyong, Director of ISS International Academy.


Students can look forward to developing critical thinking skills through technology, preparing themselves for the 21st century.

This partnership brings cross-cultural opportunities to students from both TGI and ISS International Academy. The collaborative synergies will continually inspire and empower learners to thrive in an increasingly diverse and interconnected world.
