ELS:2002 has recently switched from mailing a CD-ROM with the ELS data on it to an online downloading tool, called Online Codebook, to provide users access to Public-use data files.

Important Information About ELS:2002 Data

  • How do you figure out whether you need Public-use or Restricted-use data?
    • It depends on your variables of interest!
    • A spreadsheet for comparing the variables included in all of the ELS Restricted- and Public-use data files can be found here: ELS Variable List (960 KB)
  • Restricted-use Data can only be obtained by CD-ROM, after obtaining a Restricted-use license
    • After the license is awarded, the requested data file(s) are mailed to the license holder by express mail.
      • How long does this process generally take? Typically, 3 weeks, provided there is no problem with your license paperwork.
    • Don’t worry if your project changes: Licenses can be amended to obtain additional ELS Restricted-use data or Restricted-use data from other NCES surveys.
  • You only need to obtain one ELS data file, because each one includes all prior follow-ups
    • For example, the Public-use Online Codebook data file includes all data collected in the Base Year, First Follow-up, Second Follow-up, as well as the Third Follow-up.
