If you want to talk about ALL those topics, it is best to schedule another time, to talk with her, in more depth and to cover everything that is on your mind.
For parent/teacher conferences, they have a limited time, to talk with the parent. At my daughter's school, it is 15 minutes.
They stick to talking about academics and how your child is doing... per in class and with any academic assessments etc.
Then you also ask questions... whatever is important to you.
If you need more time, then you need to schedule a time with the Teacher, in order to cover more depth about it...
A Teacher, usually has a format they use, to go over the MANY subjects about their child. To organize it and keep it timely....
As far as other kids... yes, there is privacy about that. But you can and the Teacher CAN address your child's concerns... or what is happening. If that involves other kids, the Teacher can talk to that other child too. BUT, its not like they can tell you a whole bunch of personal/private stuff about that child or their Parent. Regardless, if anything bothers you or your child... and how another kid may be 'bugging' him... then bring it up. Especially with "Bullying" such a serious topic nowadays, in the schools. For example.
How old is your child????
For me, I always ask how my child is doing... and if on par for the grade level or if any problems or things she can work on. I also ask how I can supplement, my child's learning.... if need be.
But, I generally DO know how my child is doing in school... because I look over her homework all the time and the things/notes that the Teacher sends home weekly. And if anything, I e-mail her Teacher, to ask questions... when I need to.
I also attend the school's Open House night... and the Teacher then goes over her curriculum, the class environment, the expectations, the philosophy of her teaching approach...
I also ask my own child... HOW class is, what they do... how she feels in class... how the other kids are and if any problems... that gives me, a great 'window' of knowing, what is going on in class, with my Daughter.
all the best,
Susan
