The "Test Adaptation Reporting Standards" (TARES), or "TARES statement" was developed to alleviate the problems arising from inadequate reporting of test adaptation procedures. The TARES contains a short preamble and a checklist, that comprises an evidence-based minimum set of information for reporting in test adaptations. The TARES statement was developed by an international group of experts, under the umbrella of the International Test Commission (ITC) to support an increase in the accuracy, transparency, and usefulness of test adaptations documentation. This paper reports on the context and motivation for generating the TARES statement, describes the development process, discusses the TARES checklist structure and components, and suggests potential uses.
