How can multiple people grade assignments online so that different graders don't see each others' grades? this question is related to how you do your double blind marking for assignments, we are looking at the coursework plugin for moodle but are interested in how other other institutions do this. a specialist piece of software? paper? excel spreadsheets?

To clarify this would be two markers not being able to see the grades the other marker has assigned to the student, unless the grade is within a percentage.
This would be passed to a third marker if grades cannot be agreed upon.
This feature is currently not available in Moodle.
