@DrewDad,
The reason I have qualms about 'anonymous' is that people are quirky while filling out forms. Some people print well or poorly, some write teeny tiny or big and artfully (or not); if the test is all "blacken" the oval by filling it in within the oval lines, some are better at that hand eye coordination than others. Teachers can see how the papers are collected and remember where students sat. So I question the fullness of the anonymity.
But this is not the purview of the teaching system, in my strong opinion, to know from underage students, whether the survey completers are named or 'anonymous'. Who gave testing companies this right to invade home life? aka, private life. I'll grant if a child is abused that the child's recourse to telling a teacher and having them report it to CPS (or whatever) is ok with me. Although I posit that some of that trust may waver after this. Teachers are best at being there for the kids as wisely as they can be, but that doesn't give them automatic entry to nose on about the home. Just plain no.
As stated by me too many times, just the fact that the teacher passes out these papers sets up a mess - please the teacher, get a better report card; lie your way through the thing (either way, as some damn fool somewhere may answer the "crime" questions YES to cause trouble), or answer truthfully and set yourself up for possible prolonged observation.
I don't give a hoot about the validity (which I doubt) of the test in these conditions. Firefly is totally ignoring the elephant in the room.
