Good. You’ll have no problem signing a form the school requesting your sexual history, perversions, fetishes and gender preference either.
That would be a different kind of form. The signature on this form says “Yes, I was handed this form by my child”.
It doesn’t provide any information to the school; a signature does not indicate you have taken any action, or that you agree with the information you have been given. This is an “information” form, and parents get lots of these to sign.
Some schools make parents sign kids assignment forms, so the school knows the parents are aware of the homework the kid is expected to do.
