Thanks, I'll read through the links. The current situation is that the school extracts the data to spreadsheet; but this involves many clicks through many pages - each subject, each year group etc. It would be great just to run a script to automate this repetitive task. Any other links you have would to scripting multiple data extraction from SIMs would be most welcome. I'd like to go in and help them set something up, but want to get as much research and preparation done as possibile beforehand.
