How does your HS handle reviewing tests taken?

I am in agreement with many of the responses. Yes, I suspect the policy is in place to deter cheating. No, I really don’t want to see the completed tests and I have not requested to see any in the past or presently. But I think they can be a learning resource at times so mistakes can be better understood. My children don’t have issues with the policy. I was just curious how other schools handle the issue.
