There was a long thread about this last year. Some people thought it was appropriate to keep their Facebook friends apprised of all of their kid’s acceptances and scholarships along the way. Some thought it was never appropriate to post about their child’s acceptances. The majority thought a FB post was all right but should be left until the student has made their final decision.
I’m in this last group. Posting about acceptances your student is going to reject seems a bit insensitive to the kids for whom those same schools are dream schools. I don’t post on Facebook, so I’ll leave it to the grapevine to spread the word on where my kid going but I don’t see anything wrong with a simple “Congratulations Mykid, College X class of 2023!”
Many kids around here don’t do a formal announcement but they tell their close friends and if anyone wants to know their plans it’s pretty easy to look at their social media and see what sweatshirt they’re wearing, groups they’ve joined or college accounts they’re following.
