How is a minor's credit rating affected if signed under his parents name?

For example..if your under your parents name, is your rating affected if your parents miss payments, and how is it built and with what rating do you start initially with? Thank You

A minor wouldn't be held responsible for his parents' inability to pay the balance; hence, a minor's credit rating would not be affected if he was merely a user and not the actual account owner.
