The agency will focus its efforts around the launch of 300 international Local Access Points for the school.
Steve McComish, managing director at London PR, said: "We’re thrilled to have the London School of Marketing as a client. What the LSM is planning to achieve over the next four years is absolutely stunning and we are privileged to be playing a part in it. We look forward to a long and enjoyable working relationship with it."
The school hopes the LAPs will revolutionise the way British education is exported globally by allowing foreign students to sit a UK qualification without having to leave their country of origin.
It plans to have an LAP in every country in the world within four years.
