How school entry works
Your child’s birthday helps determine which school year they can start. Use the state or district guidance on this page; applying early does not change the birthday cutoff.

Before you enrol
Check which school serves your address, when applications open and which documents you need. If you are applying for an early start, ask about the assessment and its deadline.
What this estimate does not decide
Being old enough to start does not guarantee a place at your preferred school. A later start, a transfer or repeating a grade can change the timeline. Your child must also meet their school’s graduation requirements.
Questions parents ask
What age does my child need to be to start kindergarten in Ohio?
From the 2026–27 school year, your child’s fifth birthday must be on or before the district’s first day of instruction. Enter that date from the district calendar. It may be different from your child’s kindergarten orientation or first classroom day.
What if my child’s birthday is after the cutoff?
They will usually start the following school year. Some states or districts allow an earlier start after an application or assessment. Read the guidance on this page and ask your school before making plans.
Does this calculate my child’s graduation year?
It estimates the year your child would finish Grade 12 if they move up one grade each year. Graduation also depends on course credits and other school requirements.
Is the birthday cutoff the enrollment deadline?
No. The birthday cutoff decides age eligibility. Your school’s enrollment or school-choice deadline tells you when to apply, which may be months before school starts.
