Do you have privacy laws? Generally telling a third party someone's test results is a breach of privacy issue. Until the kids are a lot older I would campaign to get the score thing turned off and just tell the kids they did really well, well, need some work in x area etc. I would be most unhappy with them being written on the desks. That said except at university I have never come across anyone who respected privacy in education and even they slipped up.
It was also suggested at one point here that parents didn't have a right to know if the child didn't feel like sharing but that hasn't happened. They are pretty reluctant to share any results though so it does have a downside.
