A range of variables and data subsets from the QuaRCS study are available for download
By default, downloads include scores, attitudes, and demographic data from students in general education (non-STEM major) courses who completed both the pre- and post-semester assessments.
Additional options to refine your data set can be found under the Advanced tab. Sections in green allow for filtering by certain kinds of repsonses (i.e. only students in general education courses), while sections in orange allow for the inclusion of additional information, such as raw question responses.
The Data Dictionary has information on the variables in the downloaded dataset.
