This ELS:2002/2004 CDROM contains a revised version of the restricted-use base-year to second follow-up data that were previously released. Manuals documenting the sample design of these data, how they were collected, and how they should be used are included. This documentation is public use and can be downloaded directly from the ELS website (
http://nces.ed.gov/surveys/els2002 /manuals.asp).
The ELS:2002 longitudinal study is designed to monitor a national sample of young people as they progress from tenth grade through high school and on to postsecondary education and/or the world of work. By the third follow-up in 2012, these young people will be in their mid-twenties.
Users of the original second follow-up restricted-use data (NCES 2008-346) can obtain this revised version (NCES 2008-346r) by requesting it from the IES Data Security Office (
IESData.Security@ed.gov). Nearly all of the changes that have been made in the original data are in base year and first follow-up variables and not transcript or second follow-up variables.
However, none of these changes affect data that were originally released in the base year to first follow-up restricted-use data (NCES 2006-430 ), or the transcript restricted-use data (NCES-2006-351).
