Reports and Accreditations

Traill International School is subject to rigorous testing by the British Schools Overseas organisation. The term “British Schools Overseas” (BSO) may only be officially used by a school that has been inspected, within the past three academic years, by one of the inspectorates approved by the UK government’s 'Department for Education' and has been judged to have succeeded in meeting the required standards.

"The quality of the curriculum provided by the school is outstanding" 

"The welfare, health and safety of the pupils are outstanding."
