Is Preschool Required? (Do Kids Have to Go?)
By First Cubby Editorial · Updated 2026-07-04
No — preschool is not required in the United States. It’s optional almost everywhere. Mandatory (“compulsory”) school typically begins at kindergarten, around age 5–6, and the exact starting age is set by each state. Preschool is a choice, not a legal requirement.
Is preschool mandatory anywhere?
No state requires preschool attendance. A growing number of states and cities offer free or universal pre-K, but even there, going is voluntary. What’s mandatory is school starting at the state’s compulsory age — usually kindergarten, sometimes age 6 or 7.
Do you have to pay for it?
Not always. Private preschool has tuition, but there are free options for eligible families — Transitional Kindergarten (TK), state pre-K, and Head Start. See our preschool cost guide for the full picture.
If it’s optional, is it worth it?
For many families, yes — preschool builds social skills, independence, and kindergarten readiness (see what children learn in preschool). But children who stay home with rich talk, reading, and playdates can arrive ready too. It’s a personal call, not a requirement.
