# Assessment Disaggregation

## Assessment Disaggregation

- [Assessment Disaggregation](https://docs.assessmentdisaggregation.org/master.md): Disaggregates pre- and post-test answers into value-added learning scores (Walstad and Wagner 2016), adjusts for guessing (Smith and Wagner 2018), and computes gain scores (Smith and White 2021).
- [Why Do This?](https://docs.assessmentdisaggregation.org/quick-start-series/why-do-this.md): In this video we discuss why a researcher, instructor, or department might want to use the assessment disaggregation software to improve their measures of student learning.
- [Exam Files and Assessment Maps](https://docs.assessmentdisaggregation.org/quick-start-series/exam-files-and-assessment-maps.md): In this video we show how to load a pretest, posttest, and assessment map into the Assessment Disaggregation software. We then save a matched question analysis file for later review.
- [Interpreting Results](https://docs.assessmentdisaggregation.org/quick-start-series/interpreting-results.md): In the third video of the Assessment Disaggregation quick start series, we interpret the results generated at the end of video two.
- [Exam Files](https://docs.assessmentdisaggregation.org/input-files/exam-files.md): The software reads most common exam formats without modification.  Just make sure your students fill in their student id.
- [Assessment Map](https://docs.assessmentdisaggregation.org/input-files/assessment-map.md): By default, the software assumes that questions have the selected answer options (e.g. 4) and appeared in the same order on the pretest and posttest.  The assessment map can override these settings.
- [Matched Question Analysis](https://docs.assessmentdisaggregation.org/output-files/matched-question-analysis.md): The matched question analysis provides an estimate of the amount of learning when adjusted for guessing.
- [Matched Student Analysis](https://docs.assessmentdisaggregation.org/output-files/matched-student-analysis.md): The matched student analysis provides an estimate of the amount of learning when adjusted for guessing grouped at the student level.
- [Unmatched Results](https://docs.assessmentdisaggregation.org/output-files/unmatched-results.md): Unmatched results are available from the menu bar under analyze.  We recommend against these results as they aren't true measures of learning.
- [Privacy and Security](https://docs.assessmentdisaggregation.org/privacy-and-security.md): Due to FERPA, privacy and security are critical when handling identifiable grade information.  Assessment Disaggregation uses a number of technologies to keep your data safe.
