I am in SC with my 2 nieces who were just telling us they use a "clicker" in school that has A-E on it to take test. This is not with a computer, can someone please explain this to me. My sister and I are totally stumped. I also wanted to ask about getting test signed. In the schools I sub in kids have to get all test signed, my sister never sees a test. Which is the norm out there. If parents do not sign test how do they know how their child is doing? Thank you for any insights. I guess I have a very limited sample of the way things are done.
