Research Files


Downloading STAR Research Files


These research files contain results from the 2008 administration of the California Standardized Testing and Reporting (STAR) Program. Each file contains the same information presented in the Test Results section of this site and is provided to allow for more complex analyses and customized reporting of the data.

In order to protect student confidentiality, no scores are reported (or included in the research files) for any group of ten or fewer students.

Use of these research files requires some expertise in data handling. Descriptions of the file formats, instructions for accessing the data, and key points to properly manage the data are contained at the following link:
