Our Curriculum
End of Year 13: CIE AS and A2 Level Examinations
The majority of our students are full-time, i.e., they pursue an international curriculum in its entirety. We also have a small number of part-time students who study the core international curriculum in addition to following the Khmer National Curriculum.
Our Facilities
The top floor will house a large, air-conditioned Assembly-Hall, similar in size to the one in our Primary School campus. The building will have underground parking for motorcycles and general storage.
The facility will also include a specialized science laboratory, student canteen, a dedicated secure exams room as well as many more spacious classrooms.
Meet Our Team
Anyone who wants to work or volunteer at ISSR must follow our code of conduct and share our commitment to safeguarding and promoting the welfare of children and young people. We also have a strict and fair recruitment process that involves checking the background, qualifications, and references of all applicants. We do this to make sure that we only hire or accept people who are suitable and trustworthy.
All new staff and volunteers receive training on how to protect and support our students. They also agree to undergo any additional checks and procedures that our policy requires. By joining ISSR, they become part of our community and our mission to value diversity and foster respect, care and support among our students.

To ensure this occurs, a wide range of activities is organised which aids physical development and the exploration of interests as well as providing opportunities for experiencing the thrill of challenge and competition, the spirit of teamwork and a sense of accomplishment.

In certain exceptional circumstances a student may be placed one year above the prospective age range although this is at the discretion of the Principal and based upon the student’s academic background.
