The Grade Distribution report visualizes the grades of students in a course. Changes to letter grades (i.e. the boundary of a grade) can be analysed visually, saved and therefore overwritten if necessary.


Usually letter grades of a course should be communicated to the students at the beginning of a term. Occasionally it occurs that changes to letter grades are necessary. The grade distribution visualizes the grades of students. Changes to letter grades (i.e. the boundary of a grade) can be analysed visually, saved and therefore overwritten if necessary. By means of an alternating graphic chart changes can be seen immediately.


The plugin is available for Moodle 2.7+. This version is for Moodle 3.7.


  • Copy the module code directly to the moodleroot/grade/report/gradedist directory.

Bug Reports / Support

We try our best to deliver bug-free plugins, but we can not test the plugin for every platform, database, PHP and Moodle version. If you find any bug please report it on GitHub. Please provide a detailed bug description, including the plugin and Moodle version and, if applicable, a screenshot.

You may also file a request for enhancement on GitHub. If we consider the request generally useful and if it can be implemented with reasonable effort we might implement it in a future version.

You may also post general questions on the plugin on GitHub, but note that we do not have the resources to provide detailed support.
