The process of devising the short set of six questions by the Washington Group on Disability Statistics and recommendations for their use are discussed. The questions were cognitively tested to determine patterns of interpretation and out of scope patterns. Translations were made to give feasible language to get to the same concepts. Cognitive testing was then repeated to examine cross national comparability. Field testing of 1000 people followed. The importance of enumerator training and of using the exact questions and response categories is emphasised.
