With the founding of Dwight School London in 1972, Dwight became the first independent American school to establish an international campus. One of the first schools in the UK to offer the full IB curriculum for students from kindergarten–year 13, Dwight School London is a leader in the IB and was one of only six IB World Schools originally chosen from 3,700 worldwide to pilot online classes as an Open World School. Dwight School London shares this honor with Dwight in New York.

In a typical academic year, Dwight Global students are invited to participate in trips to Dwight London, such as the choral singing and learning program.
