QSI International School of Dili is fully accredited by Middle States Association of Colleges and Schools (MSA). Accreditation occurred in 2014 and is granted for seven years.

Teachers have developed committees for each of the MSA standards in order to create viable five-year plans for Facilities, School Climate, Student Life and Activities, Health and Safety, Student Services, Educational Programs, Assessment and Evidence of Student Learning, and Information Resources and Technology. The Parent Support Group and the school's Advisory Board are also partners in gathering and processing information, in order to provide a clear plan for our school.
