Ohio Kindergarten Age Checker
Enter your child’s date of birth and your school district’s first day of school, and this checker works out the first year they can start kindergarten.
Good to know
“On or before” counts. A child who turns 5 exactly on the cutoff day (or exactly on the first day of school, under current law) is eligible that year. Turning 5 the day after means waiting until the following school year.
Early admission exists. Districts may evaluate children who will turn 5 by January 1 of the school year for early entrance. It is based on the district’s evaluation, not just a parent request — ask your district early, because evaluation slots are limited.
Compulsory attendance starts at age 6. Kindergarten itself is not mandatory in Ohio, but under Ohio law a child must be enrolled in school by age 6.
How Ohio’s kindergarten cutoff works now
The rule lives in Ohio Revised Code § 3321.01, and House Bill 114 rewrote it. The bill was signed on December 19, 2025 and took effect on March 20, 2026. Under the amended law, a child is old enough for kindergarten if they are 5 years old on or before the first day of instruction in their school district for that school year. The important consequence is that Ohio no longer has one statewide cutoff date: districts set their own first day of school — most start in mid-to-late August — so the effective cutoff moves with your district’s calendar. A child who just makes it in a district that starts on August 24 might just miss it in a district that starts on August 17.
Before the change, the law let each district choose between two fixed cutoffs, August 1 or September 30, and districts were split between them. HB 114 removed that choice entirely. Any website, preschool handout or forum post still quoting an August 1 or September 30 Ohio cutoff is describing a system that ended with the 2025–26 school year.
The cutoff rules by school year
| School years | Rule | What it means |
| 2025–26 and earlier | District chose an August 1 or a September 30 cutoff (old ORC 3321.01) | Your child had to turn 5 on or before your district’s chosen date |
| 2026–27 and later | 5 by the first day of instruction (HB 114) | Your child must turn 5 on or before your district’s first day of school that year |
Worked example: a September birthday
Consider a child born on September 15, 2021, in a district whose first day of school is August 19, 2026. The child turns 5 on September 15, 2026 — almost a month after school starts — so under the current HB 114 rule they are not eligible for 2026–27, and their first kindergarten year is 2027–28. This is exactly the family the law change affects most: under the old September 30 cutoff, the same child would have started in fall 2026, a full year earlier. Move the birthday earlier and the answer flips — a child born on June 15, 2021 turned 5 on June 15, 2026, comfortably before the first day, and starts kindergarten in fall 2026 (the 2026–27 school year).
How to use this checker
1. Enter your child’s date of birth.
2. Leave the rule set to Current law, and replace the example first-day date with your district’s official first day of instruction from its published calendar — not open house or orientation day.
3. Click Check eligibility.
4. Read the result: the date your child turns 5, the cutoff that applies, and the first school year they can start. If you are comparing against older advice, switch the rule to the old cutoffs to see how the answer would have differed.
Kindergarten age questions, answered
What is Ohio’s kindergarten cutoff date?
There is no longer a single statewide date. From the 2026–27 school year, the cutoff is your own district’s first day of instruction: your child must be 5 on or before that day. Because districts start on different days in August, the practical cutoff differs slightly from district to district, so check your district’s official calendar for its first day.
When can my child start kindergarten in Ohio?
In the fall of the school year in which they are already 5 by the first day of school. A child who turns 5 before the first day — even by a single day — starts that fall. A child who turns 5 after the first day waits and starts the following fall, when they will be nearly 6.
What exactly did HB 114 change?
House Bill 114, effective March 20, 2026, rewrote ORC 3321.01 and replaced the old system in which each district picked an August 1 or a September 30 cutoff. From 2026–27 onward, eligibility turns on the first day of instruction instead. The change matters most for children with late-August and September birthdays, many of whom would have started a year earlier under a September 30 cutoff district.
My child turns 5 just after school starts. Is there any way in?
Possibly. Ohio districts may evaluate a child who will turn 5 by January 1 of the school year for early admission to kindergarten. Admission is based on the district’s evaluation of the child, not simply a parent’s request, and evaluation capacity is limited — so contact your district’s enrollment office early if you want to pursue it.
Is kindergarten mandatory in Ohio?
No. Kindergarten itself is not compulsory, but Ohio law requires a child to be enrolled in school by age 6. Families who hold a child back a year after they become eligible are within their rights; they simply cannot delay schooling past the compulsory-attendance age.
