Research File Download Instructions
 and Formats (File Layouts)

Please note that using the research files provided at this site requires expertise in the management of large data files. These files can range from 1MB up to 60MB and more and take many hours to download if you are using a 56kb modem.

Also, once downloaded, working with these files require advanced data management skills. Some of the research files are too large for spreadsheet applications such as MS Excel and Lotus. Database applications like MS Access, SAS, or SPSS will be required to fully manage these research files.

Copying individual report pages into your spreadsheet application is possible if your computer is using the most current operating systems and spreadsheet application versions.

Selecting a Research File

Research files that contain the aggregate score data for the California Standards Test, CAPA, and the CAT/6 assessments are available in two formats; fixed length ASCII and comma delimited. A state level research file containing the state, county, district, and school data for “All Students” (no demographic subgroup data) will be available in both formats. In addition, a similar state level research file containing the data for “All Sub-Groups” will be available in both formats.

The entities file contains all school, district, and county names. This file must be merged with the research file to join these entity names with the appropriate score data. A database program such as MS Access is most appropriate for this purpose.

ASCII file layouts and value lookup tables are available. Click   to view and/or download the aggregate and entities file layouts. Users of comma delimited research files will find these layouts useful in confirming the sequence of elements as well as value lookup.

A database “shell” is another alternative provided at this site. Once downloaded to the users computer, this application provides a powerful school, district, CDS, and ZIP code search capability as well as a formatted report containing all the data for the selected entity. This MS Access 2000 shell contains all entity data and is designed to import any of the selected state, county, or district comma delimited files. MS Access 2000 must already be installed on your computer.
