facebook login at school

The school can read / access my facebook page?
I received a letter from my school that have "test print" I am involved in a form of "cyber-bullying 'on Facebook. I have not found this intimidation or something representing what has been described. I fear that my school was able to see my facebook, even in the safest! Where this is my place, schools are allowed to do? Are they allowed to ask students to show your facebook (and watch out my profile on one of my friends connections)? Please Help – Thanks That's the thing I'm not cyberbullying!
No, they can not see his profile unless you have the password. They can go to other accounts, if they are authorized by the account holder, I think. They are probably not allowed to force or demand, I believe that the account owner would have to ask too much. Anyway, people could still capture all conversations, or cyberbullying, and email or print and give to the school.
