I just thought that I would add to this post. I am currently upgrading our Moodle 1.9 Grade tracker to a Moodle 2 implimentation. This has full integration with assignments and will have quizes etc. It does BTEC, Alevel and City and Guild, and will do more like cache, bespoke, functional skills, access etc. It allows all permutations of BTEC critera and units and also does unit award and qualification award calculations. The project is being funded by JISC and we have a simple Moodle 1.9 demo site with more details at http://moodlegrades.bedford.ac.uk. Our college uses our stable 1.9 version. Jisc are funding the upgrade to Moodle 2.x and our project partners are providing requirements.
Our first release to our partners will be around Easter, then another realease will be for our partners at the beginning of the summer and a comunity release for September 2013.
Thanks
