Kindergarten Cutoff Date By State
without the guesswork.
Kindergarten School Entry Age Calculator — Compare a birth date with a state reference or an exact district cutoff, including local-rule and approved-exception gates. Uses a focused calculator with visible assumptions. Inputs stay in your browser.
Age 5 on or before September 1. State references and district calendars can change, so enrollment remains unconfirmed.
Context matters.
- Age eligibility is not the same as guaranteed enrollment. Residency, documentation, program availability, readiness assessment and transfer rules can still apply.
- For states that delegate the cutoff locally, the exact district calendar is required; CalcSpan does not invent a statewide date.
- State statutes and district policies can change after the cited comparison. Recheck the district for the selected school year.

What to know before using the result.
Why does the calculator ask for the school district's cutoff?
Several states delegate kindergarten entrance dates to districts, while others allow local early-entry assessments or use the first day of school. An exact district date is more reliable than a generic September 1 assumption.
Does meeting the age cutoff guarantee enrollment?
No. Residency, documentation, program availability, transfer rules, readiness assessments and approved exceptions can still determine placement.
How current are the state references?
The national comparison is the Education Commission of the States June 2023 statute/regulation snapshot, with Connecticut's permanent September 1 change updated separately. Always reconfirm the selected school year locally.
