It contains data for individuals including responses to the background questionnaire and the cognitive assessment. Statistical confidentiality treatments were applied due to confidentiality concerns. In addition to the variables in the public use file, the RUF contains detailed versions of variables and additional data collected through U.S. specific questionnaire routing. The RUF can be accessed through a restricted-use license agreement with the National Center for Education Statistics.
