I bet most of the software they use just sucks. I've had some first hand folks tell me some of the bad stories of using various online grade book systems, and years ago I built one myself, and the accommodations people were requiring were... fairly complex. I suspect that at least in some cases I'm aware of, the vendor just lies and says "yes, we support X", gets the contract, and the end users (teachers) have to deal with the lie.
