Trio World School is a Premier British international school for boys and girls aged 2 and a half to 18. It aims to provide a broad and stimulating truly international educational experience with very high standards within the formal British Key Stages, IGCSE and A-Level curriculum while believing that school life should be valued for itself and not only as a preparation for adulthood. The heart of the school's aims is the intellectual, cultural and social development of all pupils in a context of mutual esteem and sensible good order.

There is an outstanding musical tradition which leads to a wide range of music making, much of it of very high quality, mainly as an extra-curricular activity. Drama, sport and outdoor pursuits are also very strong. The House system engenders much purposeful activity: inter-House competitions in sport, drama and music and non-competitive ventures such as fund raising for a wide variety of charities.
