Note: You are currently viewing documentation for Moodle 2.6. Up-to-date documentation for the latest stable version of Moodle may be available here: Gradebook.
The gradebook has been completely rewritten for Moodle 1.9.
The new gradebook consists of plugins for reports, imports and exports. There are a number of standard reports which are useful for graders, students etc. The grader report allows you to treat the gradebook much more like a spreadsheet with manual editing, calculations, aggregations, weighting, locking, hiding, textual notes and so on.
