ExamStat™ Item Analysis System ExamStat will be discontinued in January 2017. Exam item analysis reports will be available through LearningSuite.

Open Source ExamStat

As of June 22, 2006 ExamStat™ is available under the MIT License, allowing anyone to download, install, use and modify to fit their needs.


The current release is version 20070104 released on January 4, 2007. It contains several bug fixes over the other versions but no new functionality. It has a few bugs and problems as noted in the TODO file. However it should be stable and useful enough for most individuals.

At this point, ExamStat is only meant for system administrators and programmers. The general public will have a very hard time using ExamStat.


You can download the following ExamStat releases:
