I'm at an Australian school that until recently used Moodle. It was decided that we'd switch platforms to TASS (the Alpha School System) - essentially an admin platform, with a clunky add-on for adding assessments to it. It is a proprietary system, which may pose some problems.
I wondered if anyone had written any sort of integration to TASS. Our reporting will happen via 2 portals - Student Cafe and Parent Lounge. I "guess" mark books would need to be able to export to that platform so clients could see results.
