My son got one of these permission slips. He's 14. I promptly turned it down. I do not want some, unknown entity assessing my child. And, I believe, that if the assessment is bad, then this will stick to my son throughout his public school life. I'm sure that the information is shared with the school district. It made me shocked and dismayed.
This is the most irresponsible thing I have yet to see from our public school systems. It feels like a horrible invasion of privacy.
