Yikes! Definitely not common practice.
During Growth and Development lessons I mention that women can choose to wear a bra for comfort, and that it's a good discussion to have with your parent or come to me IN PRIVATE if you want to discuss starting, types, etc.
But I'll share this story:
The first year I was a school nurse I was working with 5th and 6th graders. I had a 6th grade girl that was developing ahead of a lot of her peers and has been wearing a bra nearly all year. We had this "stepping up" celebration at the end of 6th grade every year to acknowledge the transition to middle school (7th grade). This girl was wearing the same style of sundress (it was June and hot) as her classmates. However, it did not look the same on her because her body shape was more mature. (The way it looked at her was a violation of our dress code - which we could debate dress codes to death of course.)
I had a very good relationship with this student and the principal knew this and asked me to "talk" with her and see if she would wear her sweater during the ceremony (the principal was sensitive about the issue and did not see as a dress code violation and didn't want to treat as such so thought going to me would "help.").
Oh, this was awkward. I was a first year school nurse and didn't feel like I should have this conversation. I was debating this a lot in my head when the student did came see me on her own, wanting to check in as she had noticed that other people were, her words, "looking at her a lot." Honesty is the policy in my office and turns out she was aware and felt uncomfortable herself. She was open to wearing a sweater and wanted to do so but didn't want to draw any more attention to herself by asking to call home. She and I called her mom together and mom brought her a sweater. She was very appreciative of the call and the student really appreciated that I was honest. That student and I still have a great relationship to this day.
Now this exchange was very private and without stage whispers or another student present. Because nope. Never doing that. And as I grew into my practice, I examined my role and anyone's role in this type of discussion. As a school nurse teaching puberty I realized it was important to normalize developent as all kinds. I also realized that conversation would never happen with a student I did not have a good relationship with as well.
