The Education Trust

As well as working collaboratively with schools, The Educational Development Trust acts as an international authority on school inspection, under its own inspection framework ‘International Schools Quality Mark’. The ISQM accreditation with the Trust looks into the standards of student achievement with an effective curriculum, good use of resources, a successful leadership team; and equally strong partnerships with parents and the community to ensure students are well cared for and receive an enriched education.
