The ETS Test Collection includes an extensive library of 20,000 tests and other measurement devices from the early 1900s to the present. The collection is the largest in the world. It was established to make information on standardized tests and research instruments available to researchers, graduate students, and teachers.
The tests contained in this collection were acquired from a variety of U.S. publishers and individual test authors. Foreign tests are also included in the collection, including some from Canada, Great Britain, and Australia.
