Surveys, Questionnaires & Interviews

Gathering high-quality data about any topic begins with a survey that is well designed and easy to understand. We extensively pretest survey instruments using evaluation methods that include expert review, cognitive testing, and a variety of techniques to assess usability. If a survey includes respondents who speak a variety of languages, our translation process ensures the materials accurately capture the intended meaning.
