Southbank Westminster offers the IB Middle Years Programme (MYP) and the IB Diploma Programme (DP). It represents 61 nationalities. The IB Diploma and Middle Years Programme age groups are equivalent to middle, senior, upper or high school in other education systems.

Southbank was the first UK school to offer the International Baccalaureate curriculum to students of all ages. In the MYP (11-16 years) at Westminster, French and design technology are added to the core subjects begun in the Primary School. The MYP links traditional subject areas to one another through a holistic framework. The emphasis is on skills development and students are prepared for the IB Diploma Programme (16-18/19 years), where they choose six subjects from six subject groups: Studies in Language and Literature; Language Acquisition; Individuals and Societies (contemporary history, business & management, geography, psychology (online)); Experimental Sciences (biology, chemistry, physics); Mathematics; The Arts (visual arts, film studies, theatre arts).

Southbank Westminster is conveniently located in central London near Regent’s Park with good transportation nearby. Facilities at Westminster include five science labs, a computer lab, a hall/theatre, cafeteria, art and music rooms, and two libraries served by networked computers. The door-to-door bus service covers a wide area of central and north London.

English is the language of instruction, but students may also study their native language: currently 17 languages are offered as first or second languages. English as an Additional Language (EAL) is also offered throughout the school. Southbank attracts well-qualified and internationally experienced teachers.

Admission is based on previous school records and satisfactory references, as well as suitability of the candidate for the curriculum offered.

All students progress to universities mainly in the UK, but also around the world.
