For the 2026–27 school year, enter 2026.
The district-confirmed option is the reliable choice when local rules, calendars or waivers apply.
Used only when the district-confirmed rule is selected, or when the state delegates the cutoff locally.

Plain-date semantics · start date is not counted unless the result explicitly says inclusive.

Your result

Read before relying

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.
Rule set 2.0.0

Source & calculation QA reviewed

The calculation guide and this source trail show what the result means, where the rule came from and when it was last reviewed. This is source-and-calculation QA, not a claim of medical, legal, tax or other professional review; time-sensitive decisions still belong with the linked authority.
