Pre-K is for 4-year-olds — children in the year before kindergarten. Many programs set an age cutoff (often turning 4 by September 1), mirroring the kindergarten age cutoff a year earlier.

It's the last step on the early-years path: preschool at 3–4, pre-K at 4, then kindergarten at 5.

Pre-K vs preschool

"Preschool" is the umbrella term for early-childhood programs serving ages 3 to 5. "Pre-K" usually means the final year of that — the 4-year-old year — which tends to be a bit more structured and kindergarten-focused. For a full breakdown, see preschool vs pre-K.

What do kids learn in pre-K?

Pre-K blends play with early academics so children arrive at kindergarten ready to learn:

Letters, letter sounds, and early reading
Counting, shapes, patterns, and number sense
Following routines, taking turns, and group time
Fine-motor skills like holding a pencil and using scissors
Independence — listening, focus, and self-care

Is pre-K free?

It depends on where you live. Private pre-K charges tuition, but many states offer free or universal pre-K, and Head Start is free for families who qualify. Check your state's programs to see what's available.
