## Kindergarten entry timing: what are the options?

1. **As early as allowed**: The child starts at the youngest age the rules allow.
2. **On time**: The child starts in the year set by their birthday.
3. **Case by case**: You decide based on how ready this child seems.
4. **Delay summer birthdays**: You hold a child with a summer birthday back a year.
5. **Routine delay**: You hold the child back a year as a matter of course.

## Kindergarten entry timing: what does the evidence say?

**Experts disagree.** Credible bodies or researchers disagree — decide whose guidance you'll weigh.

## What else is worth knowing?

Children near the cutoff date may be the youngest or oldest in the class. Delaying entry, sometimes called redshirting, gives an early edge that usually shrinks over time. Local rules decide how much choice you have.

## Questions to ask each other

- When would our child be eligible, and how might that feel?
- What would make us wait a year?
- Who would we ask for advice?
