In 2009 CRELLA benefited from the donation of an extensive archive of testing materials and resources created over the last thirty years at Lancaster University. These resources contribute to the status of CRELLA as the UK's main research centre in the field, and are open to CRELLA and external staff and students.

They include materials relating to over 50 test providers and examination boards in the UK and internationally, with samples of tests, specifications and information on test development.
