Our teaching staff

UDIS attracts many applicants each year who are recruited to the school based on their experience, expertise, knowledge and fit with the core values of the school. In line with our school mission statement, we have a commitment to recruiting staff who are internationally minded and who embody the values of lifelong learners.
