ITC guidelines on adapting tests

http://www.intestcom.org/itc_projects.htm

These detailed set of guidelines should be consulted when adapting psychological and educational tests for use in various different linguistic and cultural contexts (Van de Vijver & Hambleton, 1996). This is an area of major importance as tests become used in more and more countries, and as tests developed in one country get translated or adapted for use in another.
Adaptation needs to consider the whole cultural context within which a test is to be used. Indeed, the adaptation guidelines apply wherever tests are moved from one cultural setting to another - regardless of whether there is a need for translation.
