Only under special circumstances, but otherwise no.
in Africa and uncivilized countries Yes but in a part of Asia,Europe and the US no
Yes. The doctor would not treat the child without a parent (or adult designee) present.
This depends on the state where the interview takes place. In some states, police can interview juveniles without a parent or advocate present. In cases where a parent is suspected of criminal misconduct, a court-appointed advocate is usually present to protect the child's interests.
yes you may see the doctor without a parent at the age of 16 because i did it
No, a parent must be present.
If the alleged abuse is about the parent then yes.
Yes but it depends if it involves the parent
Police are able to interview the child at the school with the principal present in cases of suspected child abuse, however, I cannot find a law that specifically prevents you from or allows you to interview the child but I would definitely not recommend it without a police officer also present. Odds are if you involve the parent you are more likely to get the truth anyways (unless you are dealing with teenagers in which case you should definitely involve your resource officer; that you could probably do)
At this age you are considered an adult . Your parents do not have to be present. They no longer are responsible for you.
the doctor decides wheather or not the parent needs to know whats going on
no
Yes. If the custodial parent fails to appear for the hearing the judge may render an order without their input.
