Before they commence classes, all CAIE teachers attend professional training conducted by Cambridge International. Subject coordinators the school executive board are in charge of identifying suitable training programmes, which may range from online courses to seminars and conferences, both locally and overseas. It is required that teachers attend such professional development programmes on an annual basis, at a minimum.

In addition, CAIE and Vietnamese teachers both participate in exchange programmes with Nguyen Sieu’s partner schools to promote the exchange of ideas and to learn from the strengths of other established Cambridge schools.
