What is the normal age of puberty?

Understand normal development in children1

The normal age of puberty in girls is between 8 and 13 years old. In boys, puberty normally occurs between 9 and 14 years old. However, because we're all unique individuals, each child can go through puberty at a different pace. That’s why it’s so important to talk to your child's doctor if you think you're seeing the signs and symptoms of puberty earlier than what's considered normal. Only a doctor can determine if your child has central precocious puberty.


As you review the signs of normal development, compare them with the signs of puberty you see in your child. If you suspect that your child is developing signs of puberty too early (before age 8 in girls and age 9 in boys) and might have CPP, print the results and discuss them with your child’s doctor. He or she may want to run some tests to determine if your child does, in fact, have CPP. Remember, only your doctor can make an official diagnosis.
