tls is a provider of international examinations and assessments to the public and private sector and one the UK’s leading language service suppliers. Our commitment to quality goes hand-in-hand with our commitment to ethical business practices. We believe we have a social responsibility to pay a living wage, treat our employees and suppliers fairly and reinvest our profits into the community.

Formed over 30 years ago in East London, tls was originally a department of the London Borough of Newham. Now an employee-owned social enterprise, we have grown to become an international organisation dedicated to the continuous improvement of service requirements and the adoption of advancing technologies.
