Researchers interested in accessing all raw data, from baseline through the fifth follow-up (2014), need to apply for a restricted-use data license at no cost through NCES’s Restricted-use License Program. Read NCES instructions for more information. All variables available across the study can be viewed through NCES Study Variable List. Survey data and documentation for the sixth follow-up will be made available to researchers shortly through the NCES restricted-use data license program.
