@GPS when you have acceptances in hand, you’ll be invited to accepted student days. You’ll have the opportunity to ask how each school does this and you’ll also be able to talk to current parents about how they managed this. Definitely take advantage of this! Figuring out how the school is making this shift from parent-driven/overseen responsibility to student responsibility is a really important part of fit, and if there are resources you know your child will need to succeed, this is also the time to understand what they are and how they are accessed.
It’s great that you’re thinking about this – there may be a path to success that doesn’t involve you seeing grades, but knowing what it is is critical. (You can always require your child to share their log-in, btw, and that option exists everywhere!)
