Pre-K (pre-kindergarten) in the U.S. is usually for children who are 4 years old, in the school year right before kindergarten.

Quick Scoop: How old is Pre-K?

  • Most pre-K classes are designed for kids who are 4 years old.
  • In many programs, children are between 4 and 5 during that pre-K year, depending on their birthday and the school’s cutoff date.
  • Some states or districts also offer “3-K” or pre-K options starting at age 3, but this is less universal and often depends on local policy and funding.

Think of it this way: if kindergarten is typically for 5-year-olds, pre-K is usually the year right before that, mostly for 4-year-olds, with some areas also including eligible 3-year-olds.
