Find out what school year a child is in based on their date of birth.

What is the UK School Year Checker?

A UK school year checker works out which school year group a child belongs to, based on their date of birth and the academic year cut-off used in England and Wales. It works by comparing the child's birth date against the 1 September cut-off: a child's academic "cohort" starts on 1 September of the year they turn the relevant age, so two children born a few days apart on either side of that date can end up a full school year apart. To work it out manually, find which academic year (1 September to 31 August) a child's birthday falls within, then count forward from Reception — Scotland uses a different cut-off (early-to-mid March), so the same birth date can map to a different year group depending on where in the UK a child attends school.

How it works

In England and Wales, the school year a child is placed in is determined by their date of birth relative to a fixed academic year cut-off, rather than simply counting years since birth. The academic year runs from 1 September to 31 August, and children born within that same window are generally grouped into the same school year and start school in the September after they turn (or are due to turn) age four or five, depending on the specific stage being calculated.

UK context

This system means two children born just a few days apart — one in late August and one in early September — can end up a full school year apart, which is a well-known quirk of the UK admissions system that catches many parents out when planning ahead. Scotland uses a different cut-off date (early-to-mid March rather than 1 September), so the same birth date can map to a different year group depending on where in the UK a child is being educated.

Tips

Always double-check the specific admissions rules for your local authority, since some details (such as deferred entry for summer-born children) are decided locally in England.
If your child was born close to the cut-off date, check both this year group and the adjacent one, since some areas allow parents of summer-born children to request a later start.
Scotland's school year cut-off date is different from England, Wales and Northern Ireland — don't apply the same rule across the whole UK.

Frequently asked questions

What is the school year cut-off date in England?

In England, the academic year runs from 1 September to 31 August, and which school year a child starts in is generally based on this cut-off rather than a simple age count — check your local authority's specific admissions guidance for exact rules.

Is the school year cut-off the same across the whole UK?

No — Scotland uses a different cut-off date (in early-to-mid March) from England, Wales and Northern Ireland, so the same birth date can result in a different year group depending on where a child is being educated.

Can parents defer a summer-born child's school start?

In England, parents of summer-born children can sometimes request a delayed start or admission outside their normal age group — this is generally decided by the local authority or admission authority, so check with them directly for your specific situation.

A quick note

School admissions rules can vary by local authority and nation within the UK — always confirm with your local authority or school admissions team for decisions that matter.
