An updated version of the NLTS2 Waves 1 through 5 data and documentation CD is now available from IES. Of special interest to researchers analyzing cross-wave, cross-source, and imputed data, new weights have been created specifically for performing these types of analyses. A new file and associated data dictionary have been added to the database that incorporate all NLTS2 weights—including the newly created weights—into a single data file. Also included in this update are modifications to documentation, data dictionaries, summarized transcript data variables, and other created variables. Listings of all updates, additions, and modifications made to the documentation, data dictionaries, and data files are included in the updated release and can be linked from the table of contents on Disk 1.

To receive the updated data and documentation, you may email a request to the IES Data Security Office.
