In the past few decades, as the United States has become increasingly linguistically diverse, public and private survey organizations have begun to address the challenges of collecting accurate, quality data from residents who speak little or no English. As a result, in recent years, survey organizations have translated data collection instruments and other materials from English into multiple languages, and they often rely upon interpreters to assist with survey interviews. Competent interpreters who have the maturity and experience to effectively communicate the complex and intricate topics covered in a survey interview are crucial to the data collection process and to protecting the rights of Limited English Proficient (LEP) respondents. Executive Order 13166, signed by President Clinton in 2000, requires federal agencies to develop and implement systems to provide meaningful access to LEP residents.
