A well constructed rubric is a great way of  communicating, both to students and fellow assessors, exactly how the marking of an assignment is being approached but the construction of effective and comprehensive rubrics can be very time consuming.

Recently, while looking through the instructions for entering rubrics in the peer assessment workshop activity in Moodle, I came across a link to a site with hundreds of example rubrics.
Usefully, the site also allows users to construct their own rubrics in a rich variety of subject areas. The site is free, easy to use and well worth a look for anyone needing inspiration in this area.
