The ITC Guidelines for Translating and Adapting Tests (Second Edition)

The second edition of the ITC Guidelines for Translating and Adapting Tests was prepared between 2005 and 2015 to improve upon the first edition, and to respond to advances in testing technology and practices. The 18 guidelines are organized into six categories to facilitate their use: Pre-condition (3), test development (5), confirmation (4), administration (2), scoring and interpretation (2), and documentation (2). For each guideline, an explanation is provided along with suggestions for practice. A checklist is provided to improve the implementation of the guidelines.

The Council of the International Test Commission wishes to thank the six-person committee who worked for several years to produce the second edition of the Guidelines for Translating and Adapting Tests: David Bartram, SHL, UK; Giray Berberoglu, Middle East Technical University, Turkey; Jacques Grégoire, Catholic University of Louvain, Belgium; Ronald Hambleton, Committee Chairperson, University of Massachusetts Amherst, USA; Jose Muniz, University of Oviedo, Spain; and Fons van de Vijver, University of Tilburg, Netherlands.

Also, the International Test Commission wishes to thank Chad Buckendahl (USA); Anne Herrmann and her colleagues at OPP Ltd. (UK); and April Zenisky at the University of Massachusetts (USA) for their careful review of an earlier draft of the document. The ITC is grateful too to all of the other reviewers from around the world who directly or indirectly have contributed to the second edition of the ITC Guidelines for Translating and Adapting Tests.
