My adult kids have graduated many years ago. I didn’t bother for them to sign any consent because my sister (lawyer) told me I didn’t need to bother. Over 8 years they were in college, I have had many dealings with the school and I never had any issues on getting necessary academic information. I would say every time it was at my kids’ requests to help them resolve some issues.
The school can also disclose PHI information if it’s related to drug usage or potential of student committing self harm.
OP seems to have some issues with his daughter that he needs to resolve. All of us on this forum are both parents and children. I would say most of us do not have real desire to have NC with our parents unless under some extreme circumstances. Hard for me to believe so many young adults want nothing to do with their parents.
Are you paying for your daughter to return to school for sophomore year? Because unless you are - it doesn’t matter if the bill is $45k or $85k if she can’t pay for it herself - she won’t be going back.
If you are paying for her to go back for sophomore year (quite frankly the tack I’m hoping you take for multiple reasons even if she remains no-contact during the upcoming year) - then congratulations at having a much lower college bill than you were expecting you might have to pay.
@ArtsyKidDad im sorry for the situation you are dealing with.
I guess the only thing I would want to know is if your daughter chooses to drop out of school after you have made the fall payment but in time to get a refund of part of all of that payment…will YOU get that refund? Because I think it would be sent to your daughter…
ETA…I hope the daughter stays in college and I think she will.
As I commented in your previous thread, student info is blocked by default. They don’t opt in to FERPA protections, they opt out. Your daughter didn’t need to “place confidentiality flags” on her records to prohibit you from accessing them. You are prohibited by default. If the student wants to OPT OUT, they can sign the waiver to allow the parents access. At the school I work at, students can sign a waiver for just the financial stuff (academics are still confidential), or they can sign the full waiver to allow the parents to see the grades as well.
Regardless of individual professors or departments or universities revealing protected info without permission, most of them take the privacy laws pretty seriously and abide by them.
I am a prof and I can see if the students have signed the waiver or not. If they haven’t, I absolutely refuse to discuss any aspect of their performance with their parents. Even if they’ve signed the waiver, I gently suggest that the parent help the student learn to advocate for themself (unless it’s some sort of emergency of course). I rarely get parents contacting me as it is.
I will encourage my child to NOT waive his FERPA rights. I could see certain circumstances where it might be a good idea, but for the typical kid, I think it’s best to keep the FERPA intact. My friends said it was a little strange when their son who is newly 18 went to the pediatrician for his yearly checkup. The docs asked the parents to stay out of the room. Obviously, their child could have allowed them in, but I think the peds are trying to help the kids transition to independence.
I know your situation is kind of unique, but these laws exist for good reasons, and every professor I know supports them.
Since you are coming back to the topic, I need to apologize for not using my words more precisely, she opted in, then, she opted out.
On a lighter and completely unrelated topic: I would love to be a student of a professor whose username on CC is ColdWombat 
My kids’ pediatrician kicked me out around age 11, once they turned 18 they went without me.
