International School of London

The International School of London opened in 1972 and offers one of the oldest International Baccalaureate (IB) programmes in the world for students aged 3-19. Our award winning co-educational school provides an education that focuses on developing critical thinking skills and experiential learning to prepare young people for a modern world. Students are respected as individuals, are academically challenged and individual attention to student development is provided through small class sizes.

How do you get in?

Prior to an application, parents are welcome to visit ISL and discuss their children's schooling needs. This can be done by telephoning or e-mailing the Admissions Office to arrange a convenient date and time. Most students join the International School of London in September, but we are happy to admit students throughout the year provided that we have places available.
