This collection is not extensivley international in scope but is primarily a free public repository for over a dozen important American educational datasets including longitudinal studies, produced by the U.S. National Center for Education Statistics (NCES). Data analysis can be conducted using the IAED Survey Documentation & Analysis (SDA) system. Abstracts, related publications and sites are also available.
On the download page a choice of uncompressed or compressed files is given with file sizes noted. The compression format, gzip, is a Unix format, but can be opened with Winzip on PCs. For some confidential surveys, a Windows-based table viewing software is required to look at the aggregate data.
Data freely available on the internet. Registration is required. By submitting their email address only, users can download the raw (ASCII) data and corresponding codebook documentation.
