cApStAn's role in knowledge and skills

In the last two decades, there has been a spectacular proliferation of large scale comparative assessments, in which cross-linguistic, cross-regional and cross-cultural equivalence is a requirement. cApStAn has played a pioneering role in organising and documenting sophisticated translation and adaptation models for these surveys: in close collaboration with psychometricians and researchers, translation verification checklists have been developed. Linguistic and formal features that play a role in driving psychometric properties of items have been identified; and linguists have been trained to apply standardized reviewing and documentation criteria.
