Arizona Kindergarten Age Cutoff — Plus Preschool & TK (2026–2027)
In Arizona, a child must turn 5 by September 1 to start kindergarten that fall. Arizona does not have a statewide Transitional Kindergarten grade; children go from preschool/pre-K to kindergarten. Arizona has no statewide public pre-K program open to all families; most preschool is private (tuition-based), with Head Start for eligible families.
