The Assessment Data Dictionary included fields from student assessment data exports. Exports can display in one of two ways: pivoted and unpivoted. The fields available will vary depending on the type of export and assessment type.

Default Export Format

This is the default for data exported through the reporting website. This data is pivoted, and each assessment in the export has its own column. For more information on running reports and exporting data, please visit Export Data and Print Reports.
