Matching grades: UK Year, US Grade and Korean school year
A UK Year number is one higher than the US Grade for the same child. Korea groups children by calendar year and starts in March, so birthdays can shift a child by one grade.

This guide is for parents who are unsure which grade their child will enter abroad. British, American, Korean and Japanese schools use different cut-off dates and grade names. Here are the official rules and some birthday examples.
The key rule: UK Year = US Grade + 1
British schools count Reception, then Year 1; American schools count kindergarten, then Grade 1. So the same child's British year number is one higher than the American grade.
- UK Year 7 = US Grade 6
- UK Years 12-13 are the A Level stage (sixth form).
Cut-off dates by country
UK: born 1 September to 31 August
For 2025/26, Year 1 is born September 2019-August 2020 and Year 7 is born September 2013-August 2014. Reception is the foundation stage (EYFS), Years 1-2 are KS1, Years 3-6 KS2, Years 7-9 KS3 and Years 10-11 KS4.
US: depends on state and district
The US has kindergarten then Grades 1-12, and children usually start Grade 1 around age 6. Age cut-offs and school bands depend on state and district rules, so check the district you are moving to.
Korea: calendar-year cohorts, March start
Under the Elementary and Secondary Education Act, children start primary school on 1 March of the year after they turn 6. Children born in 2019 start in March 2026.
Japan: April start
Children born between 2 April and the following 1 April share a grade, and placement is by age.
Birthday examples (2025/26)
- Born January-August 2019: UK Year 2; US Grade 1 in a district with a 1 September cut-off; Korean primary year 1 from March 2026
- Born October 2019: UK Year 1; kindergarten in that US district; Korean primary year 1 from March 2026
Children born September-December are the most likely to sit one grade apart between UK/US schools and Korea. Keep this in mind if you plan to return.
Checklist
- Have you noted your child's birth date and current grade?

- Have you thought about how grades continue if you return to Korea?
Ask the school
