Our highly qualified and multinational staff have taught in over 20 countries and bring an impressive range of qualifications and experience to ISZN, whilst also speaking more than a dozen different languages between them. Although they possess a wealth of educational experience, as lifelong learners, all staff regularly review current educational theory and practice both by distance learning and through training courses.
In addition to our full-time teaching staff, we also employ a substantial support staff of learning assistants, office staff, drivers, cleaners and caterers, each of whom plays a vital role as part of the ISZN team.
