Khmer lessons at PIO follow the Cambodian national curriculum. PIO has had an MOU with the Ministry of Education, Youth and Sport (MOEYS) since 2004. In 2016 that MOU was extended to cover high school classes (Grades 7 - 9) and primary classes at the Borey Santepheap 2 School.

PIO is required to report to the Ministry on a regular basis and there are monitoring visits to ensure that the school is meeting the standards required by the ministry.
