St George's provides a British-system education, with a rigorous academic programme, and many extra curricular activities.

There is a strong EAL programme in small sets in all except the final years and also provision for students with special educational needs.

Sports facilities include a running track, grass fields for football, rugby and cricket, astroturf tennis courts, and all-weather hockey, volleyball and basketball courts.

Teachers are almost all from UK, holding university degrees and on average have 8 years of teaching experience. All teachers participate in pastoral care and guidance through a House system.

Specialised UK and US careers advice is available. Most pupils go on to universities or other higher education, the majority to UK universities, but also to the USA, Italy and elsewhere.
