Misbehaviour in school then yes of course the teachers can do it. Schools have their own rules just like parents have their own rules for kids.

It really depends on the situation. If the kid misbehaves in school or disrespect others then yes else I would discipline my kids myself

There are many mentors who can help my son so if they are in the right and gives reasonable discipline, I am ok

Discipline with explainations and from your heart. That kind of discipline i am really thankful.

I let the teacher to reprimand them. But no physical contact. I want my kids to respect people

To survive in the world they need to know how to take everything positively

Eg. If he misbehave in school and the teachers informed me in advance

Within reason for sure. They need to learn if they did wrong

Sometimes where appropriate and without rudeness is fine

If their way of discipline is same as me, I'm still ok.
