ETS has been working for more than 70 years to design tests that help to advance quality and equity in education worldwide. Created in 1947, ETS (Educational Testing Service) is a private organisation dedicated to the research and the conception of tests assessing and measuring performance. All of its tests are designed in Princeton by statisticians, psychometricians and researchers. ETS is now the world's largest private educational testing and measurement organisation, and continues, through rigorous research, to create high-quality assessments that: accurately measure student performance do not disadvantage any group of test takers because of differences in personal characteristics such as race, ethnicity, gender or disability For more information on the development of our tests, click here.
