Delaware Kindergarten Age Cutoff — Plus Preschool & TK (2026–2027)
In Delaware, a child must turn 5 by August 31 to start kindergarten that fall. Delaware does not have a statewide Transitional Kindergarten grade; children go from preschool/pre-K to kindergarten. Delaware's public pre-K program, Early Childhood Assistance Program (ECAP), is available to eligible families (income-eligible (at/below poverty) 3- and 4-year-olds).
| Kindergarten cutoff | Turn 5 by August 31 |

Delaware age cutoffs — the details
Kindergarten and TK cutoffs are set by state law; preschool has no legal age cutoff because it is private. Cutoff verified from the official Delaware source. Always confirm the current date with your school or district — rules can change year to year.
